Talc possesses chemical inertness, high dielectric strength, high thermal conductivity and low electric conductivity which make it useful for ceramic and refractory applications. Talc acts as a flux by lowering the firing temperature and quickening the firing time.
Talc increases thermal shock resistance, electrical resistance and thermal expansion at elevated temperatures, thereby preventing glaze cracking.
Our talc products, Supra & Ceram-II possess high temperature resistivity and low level of impurities, thus, making it favourable in the manufacturing of ceramic bodies, tiles and insulators. It also possesses low thermal expansion and dimensional stability along with low dielectric loss. These properties make it very useful for electrical porcelain, stoneware application. Due to high chemical purity with high whiteness, some of premium grades are preferred in Ceramic glaze application. Their low iron content makes it preferable for electro ceramic application.
