Sillimanite in Electrical Components

silimanite-4Due to its low electrical conductivity and high thermal stability, appreciable quantity of sillimanite powder mixed with high-grade china-clay is used in the manufacture of spark plugs and other insulating materials required at high voltages.

Anand Talc offers high purity sillimanite powder containing minimum iron oxide, which would otherwise alter the electrical conductivity of the product.
