Use Of Talc In Ceramics

Being one of the major consumers of the industrial minerals, the Ceramic industry uses Talc for variety of products. It uses talc for “body” and glazing of products such as Electrical Insulating (Steatite Talc), Sanitary Ware, Wall tiles, Porcelain Dinner Ware. Talc Suppliers provide talc used in this industry that is generally of 80 ~ 93% whiteness and 200 – 300 mesh. Enstatite is formed as talc disassociates during firing which produces high thermal expansion bodies, resulting in glazes being put into compression and thereby minimizes crazing. Low moisture expansion bodies are produced as a result, which results in good resistance to delayed crazing. Talc's massive nature helps in the process of dry pressing and in preparation of good casting slips.

Because of the use of talc, low firing temperatures are possible. Over a wide temperature range the shrinkage and absorption properties of bodies are fairly constant. High quality white fire bodies are possible because of this. High-talc bodies can be reafily fitted with glazes of unusual brilliance and attractiveness. Talc Manufacturers also used talc in manufacturing of high-frequency electric insulators by means of steatite bodies, a segment of the ceramic white wares market. Talc is sometimes used as an additive in dinnerware bodies composed of clay, feldspar and flint. Compromising as much as 6% of such bodies, Omcera provides greatly improved craze resistance. OMCERA exhibits the following characteristics.

• Uniform Chemical composition.
• Constant amount of shrinkage on firing.
• Fired color.
• Particle size distribution.
