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.
