Ceramic raw materials ceramic binder
Ceramic kiln is an equipment to do burning to the ceramic biscuit. By having the burning, the biscuit complete the oxidization or reductio process and becomes pottery or porcelain. The craftsmen in the filed often say that ceramic kiln is the key equipment and burning process is the key process in ceramic making.
Ceramics: wollastonite can be used in a variety of ceramic applications including ceramic glazes and bodies, enamels, frits, fluxes and in sanitaryware. This industrial mineral is a source of cao to alkaline glaze formulations to improve the strength of the glaze. Wollastonite also has a low loi (< 1%) which gives minimal gas evolution during firing resulting in a smooth surface with diminished pinholing. Due to its acicular structure, wollastonite improves green strength and reduces crazing and checking especially during rapid heating and cooling. It has a low sintering temperature (approximately 991-1196c) which is comparable to that of most natural frits. Specification: Sio2:45-56%, Al2o3
What is Ceramic Body Binder? Binders are glues that harden ceramic powders as they dry. They enable to improve surface adherence and slower drying. Mainly Binders are substances that improve the mechanical strength of green ceramic bodies so they can pass through production steps before firing and without breakage. What are the Purposes of using Ceramic Body Binder? Binders are basically glue, they are designed to harden and strengthen bodies and glazes as they dry. Ceramic Powders containing binders can exhibit remarkable surface adherence and durability on drying. Ceramic Powders containing binders can exhibit remarkable surface adherence and durability on drying. Binders are specially important in glazes, bonding them to even dense bisque surfaces.

In many cases, Binders addition to bodies are essential. Binders are used in ceramic industries to provide green strength so that the body will simply maintain its shape until it is sintered. In many cases, the green ceramic body has to be machined, inspected, stored and placed onto setters for firing, often by workers who are not perfectly careful, so considerable strength would have to be provided by the binder. What are the Negative Effects of Using a Ceramic Binder? Binders come at a cost. They can be very expensive. They slow down drying. They make slurries messy & difficult to process and handle. Cleanup is much more difficult. They generate carbon dioxide as they decompose during firing. In some industries like tiles, binders are avoided where possible or carefully chosen and monitored

Alumina ceramics is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness. High purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential. Alumina ceramic is the material of choice for alumina wear parts. The proven wear and heat resistance of alumina wear parts makes them ideal for the manufacture of wear-resistant components. Alumina has a high melting point, high hardness, although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity. Good chemical stability of alumina leads to high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications. Alumina Ceramics are generally white and the color is derived from either the sintering additives or impurities in the raw materials. We make and supply alumina ceramic grinding media, abrasion ceramic lining and alumina ceramic parts & components. We also supply zirconia ceramics.
The nepheline syenite can be used in float glass, container glass, fibre glass, opal glass, sheet glass, electrical glass and tableware glass. Nepheline syenite provides necessary additions of alumina and alkali in the glass batch. It has low in silica and contains no free quartz. It also has a favorable ratio of sodium oxide to potassium oxide of 2: 1. Nepheline syenite makes glass batches to have lower viscosity and easier workability compared with potash feldspar. Its high alumina and alkalis content also makes it so suitable for the glass manufacturing. 1. The content of potassium and sodium is high in nepheline syenite, and it can partly replace the soda ash in glass batches. 2. The characteristic of foidal minerals are they will not intergrow with quartz. They can decrease the melting temperature with reaction between nepheline syenite and quartz in glass furnace. The melting temperature would be 40° c lowered than feldspar. 3. The content of al2o3 is high and the content of sio2 is low in nepheline syenite. So it can save the cost of transportation of al2o3. 4. It can decrease the content of fe2o3 in glass.
