Kyanite is a typically blue silicate mineral, commonly found in aluminium rich metamorphic or sedimentary Rocks.Kyanite is a member of the alumino-silicate series, which includes the polymorphs, alusite and sillimanite, which have the same chemical composition (Al2O3.SiO2) as alusite and sillimanite but it is distinguished from those two minerals by its physical properties. Refractory Materials : Refractories are heat-resistant materials that constitute the linings for high-temperature furnaces and reactors and must be able to withstand high temperatures, mechanical wear, thermal shock and chemical corrosion. Kyanite is used in refractories sometimes in raw form and mostly in calcined form. 1. Raw kyanite: Kyanite has high expansion coefficient. Moreover, its calcination into mullite is also accompanied by a significant expansion in volume (20%). Raw kyanite as a refractory material is thus particularly beneficial when shrinkage from other materials and binders needs to be compensated for. 2. Calcined kyanite: Kyanite calcined to mullite is widely utilized in refractory products. Mullite exhibits excellent refractory properties like thermal stability (it is stable upto 1810 C), thermal shock resistance, creep resistance, and high hot strength and chemical corrosion resistance. Refractory bricks made from calcined kyanite possess outstanding: Higher modulus of rupture. Lower co-efficient of expansion. Increased firing range and temperature. Increased durability, about three times that of ordinary bricks. More resistance to salt attacks. Very low co-efficient of spalling. Kyanite refractories find application used in glass industry as well as various metallurigical industries (except steel metallurgy, as mullite refractory bricks are corroded by iron slag and are not highly resistant to metallic oxides). Kyanite has been a supplier of raw kyanite for many years. Our kyanite is high in purity, free from iron oxide, silica, bases and alkalis. These impurities considerably reduce the softening point of mullite and thus affect the refractory properties. kyanite is often associated with the mineral corundum. This is advantageous as it reduces the percentage of free silica when calcined. All in all. Specfications : Al203:- 35-52% Fe2o3:- 1-5%
In the gem world, all kinds of gem-quality corundum other than ruby are called sapphire. The mineral name of sapphire is corundum, which belongs to the corundum group of minerals. In fact, the gem-quality corundum in nature is called sapphire, or colored sapphire, except for red called ruby, and other colors such as blue, light blue, green, yellow, gray, colorless, etc. Sapphire is preceded by a color name, such as pink sapphire. The chemical composition of sapphire (Al2O3) is mainly Fe, Ti, and color. Corundum contains iron (Fe) and titanium (Ti) and other trace elements, and presents blue, sky blue, light blue and other colors, among which the royal blue and cornflower colors that are considered to be thick but not black are the best. In cabochon cutting, when the interior is rich in three groups of inclusions parallel to the bottom surface and oriented, it can produce beautiful six-shot starlight, which is called star sapphire The composition of sapphire is alumina, which is blue due to the trace elements titanium (Ti4) or iron (Fe2). It belongs to the trigonal crystal system, and the crystal form is often cylindrical, short column, plate, etc., and the geometry is mostly granular or dense block. Transparent to translucent, vitreous luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous body. Sometimes it has a special optical effect - the star effect. The hardness is 9, and the density is 3.95-4.1 g/cm3. No cleavage, fissure development. Industrial sapphire is a material used in special vehicles as transparent armor, and with the exception of diamonds, sapphire is harder than any other natural material. Sapphire belongs to the trigonal crystal system and has a hexagonal structure. The lattice constants are: a=b=4.758A, c=12.991A Refractive index 1.762-1.770 Birefringence: 0.008- 0.010 Uniaxial crystal negative light, in some cases abnormal biaxial crystal light Luster: bright glass luster to adamantine luster Pleochroism: Colored sapphires have dichroism, generally, dark blue/blue, blue/light blue, blue-green, blue-gray, yellow sapphire has golden/yellow, orange/light yellow, light yellow/ Colorless, wait.
Honing refers to a set of stones (sticks) assembled on the honing head put pressure on the work-Piece along the radial, and through rotating and moving back and forth for precision honing machine. When honing high hardness and toughness materials, the Diamond /CBN Efficiency of honing stone( stick) is 3-75 times higher than that of ordinary abrasive stone, and the honing efficiency of ordinary materials is also improved about 10 times. since Diamond/CBN honing stone (stick) wear is less, the shape retention is better, therefore, the higher honing accuracy and economic effect can be obtained. Diamond honing stick is used to process hard and brittle materials, such as honing high carbon steel, cast iron, cemented, carbide, etc. honing stick mainly used for honing high strength alloy steel, tool steel, stainless steel heat-resistant alloy steel.
