Talc Powder

Talc is widely used in the ceramics industry in both bodies and glazes. It is increasingly being used in the manufacture of artwares, jars, wall and floor tiles. It serves as a non-plastic ceramic material.The proportion of talc in the ceramic body may go upto 80%.

It has good refractoriness. Talc converts into enstatite at 1300º C. Between 800ºC to 840ºC, the water molecules start being driven off and talc dissociates into enstatite and amorphous silica without undergoing any change in shape, the shrinkage being 0.0005 inch only.
