Talc in Ceramics, Dentifrices and Electrical Industry


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%

  • Talc is highly white as well as bright and thus imparts appropriate visual properties to the ceramic product.
  • 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.
  • In stonewares, small percentages of talc are used to flux the body and therefore improve strength and vitrification.
  • It is a source of MgO flux in high temperature glazes to control melting temperature. It is also employed as a matting agent in earthenware glazes and can be used to produce magnesia mattes at high temperatures.
  • The addition of talc in suitable proportions in the body of mixtures for porcelain, jars prevents the crazing (cracking) effect on the glazes. In addition, talc imparts smooth buttery surfaces to the glaze.

Anand talc manufactures numerous grades for the Ceramic industry. We can supply to the Ceramic industry for any product that can be named from artwares, pottery, porcelain, tiles to sanitary ware. Our talc due to its whiteness and purity performs very well in these products. Moreover, our range of grades implies that we can offer suitable products at different price points to optimally suit the customer’s functional requirement as well as budget.


Dentrifices are prepared by mixing suitable proportions of polishing agents like talc, precipitated limestone, kaolin, calcium sulphate, calcium phosphate with gum, glycerin, soap and other chemical ingredients. In the Manufacture of Dentrifrices, some quantity of talc is used as a polishing agent.

For use in Dentrifices, high whiteness is critical. Talc is thus, a well suited option as an ingredient for dentrifices. In addition to high whiteness talc also imparts smoothness to the final product. Anand talc is able to offer talc of extremely high whiteness perfectly suited for use in dentrifices.


Talc is a poor conductor of electricity and is thus used in the manufacture of ceramic goods required for the Electrical industry. For this purpose talc must be high in purity. Iron oxide should not be more than 1% which would otherwise increase the dielectric constant of the product as well as impart an unattractive color to it.

The CaO should not be more than 1.5% as it would increase the abrasiveness, shorten the vitrification range and sometimes cause shrinkage during high firing. Anand Talc is equipped with powerful magnetic separators to reduce iron impurities. In addition, it boasts of stellar laboratory facilities that ensure tight monitoring of calcium levels, whiteness, brightness to name a few. Thus, it is able to supply high grade talc of uncompromised purity.
