Talc
Magnesium silicate
The term talc refers both to the pure mineral and a wide variety of soft, talc-containing rocks that are mined and utilized for a variety of applications. Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).
Uses
Ground talc is used as an ingredient in ceramics, paper, paint, roofing, plastics, cosmetics, talcum and baby powders, and a variety of other assorted uses such as making rubber and plastics.
Element Type 1
Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO2). Silicon compounds are the most significant component of the Earthâ??s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silicate ion SiO44- in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals. Silicon alloys include a variety of metals, including iron, aluminum, copper, nickel, manganese and ferrochromium.
Uses
Ferrosilicon alloys are used to improve the strength and quality of iron and steel products. Tools, for instance, are made of steel and ferrosilicon.
In addition to tool steels, an example of â??alloy steels,â?? ferrosilicon is used in the manufacture of stainless steels, carbon steels, and other alloy steels. An alloy steel refers to all finished steels other than stainless and carbon steels. Stainless steels are used when superior corrosion resistance, hygiene, aesthetic, and wear-resistance qualities are needed.
Carbon steels are used extensively in suspension bridges and other structural support material, and in automotive bodies, to name a few.
Silicon is used in the aluminum industry to improve castability and weldability. Silicon-aluminum alloys tend to have relatively low strength and ductility, so other metals, especially magnesium and copper, are often added to improve strength.
In the chemicals industry, silicon metal is the starting point for the production of silianes, silicones, fumed silica, and semiconductor-grade silicon. Silanes are the used to make silicone resins, lubricants, anti-foaming agents, and water-repellent compounds. Silicones are used as lubricants, hydraulic fluids, electrical insulators, and moisture-proof treatments.
Semiconductor-grade silicon is used in the manufacture of silicon chips and solar cells. Fumed silica is used as a filler in the cement and refractory materials industries, as well as in heat insulation and filling material for synthetic rubbers, polymers and grouts.
Silica is used in ceramics and in making glass.
Silicon is considered a semiconductor. This means that it conducts electricity, but not as well as a metal such as copper or silver. This physical property makes silicon an important commodity in the computer manufacturing business.

uses:
1- calcinated gypsum is about 95 % of gypsum uses that we heat the gypsum to 130 degree which remove water and become hemi hydrated gypsum that called plaster of paris, it used in wall plaster, wall lining, plaster board, wall board, tiles for ceikings, partitions. Thermal isolation, regulator to moisture measurements.
2- add Uncalcined gypsum crushed from 3 to 6 % to produce Portland cement so solidification speed become low.
3- gypsum contain 15-20 % sulfur produce ammonium sulfate which act as natural fertilizer.
4- glass industry to easily remove the gases.
5- fine gypsum use in resin industry, paper filler, in soil used in drilling petroleum well.
• by heating to 1093 degree, calcium sulfide form which produce sulfuric acid and lime.
• A binder in fast-dry tennis court clay.
• Plaster of Paris (surgical splints; casting moulds; modeling).
• A wood substitute in the ancient world; for example, when wood became scarce due to deforestation on Bronze Age Crete, gypsum was employed in building construction at locations where wood was previously used.[19]
• A tofu (soy bean curd) coagulant, making it ultimately a major source of dietary calcium, especially in Asian cultures which traditionally use few dairy products.
• Adding hardness to water used for homebrewing.
• A component of Portland cement used to prevent flash setting of concrete.
• Soil/water potential monitoring (soil moisture tension).
• A common ingredient in making mead.
• In the medieval period it was mixed, by scribes and illuminators, with lead carbonate (powdered white lead) to make gesso which was applied to illuminated letters and gilded with gold in illuminated manuscripts.
• In foot creams, shampoos and many other hair products.
• Impression plasters in dentistry
Mica are sheet silicates historically significant for their ability to be split into large, thin sheets that are uniquely useful for their electrical, thermal, and mechanical properties. They have high electrical and thermal insulating properties; they are resistant to chemical attack; they can be split into
transparent or optically flat films; and they can be cut or stamped to shape.
Uses of mica:
1- Joint cements: muscovite is used in drywall joint compounds, where it contributes to consistency and workability, smooth surface finish, and resistance to shrinkage and cracking.
2- Coatings Fine-ground, -325 mesh and micronized mica grades are used in paint as a pigment extender and for dry film reinforcement. The inert, platy mica improves suspensi
on stability, controls film checking, chalking, shrinkage, and blistering, improves resistance to weathering, chemicals, and water penetration, and improves adhesion to most surfaces. Coarser grinds are used in textured paints, and wet-ground mica is used in high quality exterior house paints. High aspect ratio grades are preferred for porous surface sealers
to seal pores, control penetration, and reduce sagging and film cracking.
3- Plastics Finely ground, -325 mesh and micronized micas are used in plastics to improve electrical, thermal, and insulating properties. Mica is considered the most effective mineral for reducing warpage and increasing stiffness and heat deflection temperature in plastics. In general, mica reinforces crystalline better than amorphous polymers. Best results are obtained with nonpolar polymers when mica is pretreated with a coupling agent to improve wetting. Mica is used in both thermoplastics and thermosets. Its largest single use is in
polyolefins, even though it requires stabilizers to prevent degradation of polypropylene.
4- Drilling fluids Coarse, hammermilled (+10 mesh) mica is used in waterbased oilwell drilling fluids to prevent fluid loss into porous rock formations.
Also known as ground quartz and silica flour, is produced by grinding high-purity quartz, quartzite, sandstone, or silica sand to finer than 45 micron. Air separation is used as required to remove kaolin, mica, feldspar, or calcite impurities.
we can crush also reach 45 micron with magnetic separation
Uses:
1- glass industry
2- lenses industry
3- television, radio, computer, radar, transmission machine industry
4-pure quartz for photocells
5- semi conductor industry
6-Cleaners
7-Paint
8-cramics: Low-iron ground silica, typically -200 mesh, and calcined silica are used in whiteware formulations to facilitate drying of the body, to control expansion characteristics and compatibility between the body and glaze to prevent crazing, and to provide whiteness and acid resistance.
10-Coatings Ground quartz and novaculite are used as extender pigments because of their low binder demand, which allows high loadings.
11-Rubber Finer (<0.025 micrometer) precipitated silica is the only fully reinforcing alternative to carbon black for general rubber compounding. Most of the precipitated silicas used in rubber are reinforcing grades rather than the coarser extending grades. Precipitated silica is used in compounds designed to be translucent or colored, and in general compounding to promote abrasion resistance, cut growth resistance, tear strength, elastomer-to-textile adhesion, and resistance to heat aging.
12- Plastics: are used as thixotropes in unsaturated polyester resins and gel coats and in epoxy resins. Fumed and precipitated silicas are used as thixotropes in PVC plastisols. used as ant blocking and antislip agents by temporarily absorbing plasticizers that can cause tack and by providing an imperceptible surface roughness. They are used as matting or flatting agents and as plate-out agents in highly plasticized compounds.
