Soapstone powder is additionally written as H2Mg3(SiO3)4 (Magnesium Silicate), that corresponds to four.8% H2O; 31.7% MgO and sixty-three. 5% SiO2. It is basically a secondary mineral fashioned by the hydrothermal actions and the processes geological process of magnesium-rich rocks like dolomite, pyroxenite, metamorphic rock, serpentine, dunite, and mineral. In pulverized form, it is whiter in appearance. The compact style of talcum powder is termed soapstone or talcum. The word talcum powder has been named in all probability because of its saponaceous feel. The impure and hard variety is called potstone, which is mainly utilized for making carvings, models, decorative vases, utensils, pots and the like and hence the name potstone. French-chalk is that the brand name of fine-grained talcum powder of pure white quality that forms the bottom for several cosmetics and bathroom preparations. Talcum powder is valued for its extreme softness, smoothness, high lubricating and hiding power and ability to absorb oil and grease. It is chemically inert to acids and alkalies. It has been found to be a superb filler. It can withstand temperatures up to 1300ÂșC. It has low electrical and thermal conductivity. Above all it can be easily powdered, cut and sewn into any shape and size. These properties in talc are of extreme value for various industrial applications described later in this chapter. Soapstone powder is found in three forms, fibrous, nonfibrous and massive. The fibrous selection consists of wealthy proportions of asbestos, amphibole, and curved. The nonfibrous variety contains mostly of serpentine and carbonates. Fibrous variety is slightly difficult to grind.

Industrial Application

Pulverized soapstone powder has wide industrial applications as filler in rubber, textile, plastic, linoleum, asbestos products, polishes and soaps; as a loading agent for paper of all kinds; as a carrier of insecticidal and pesticidal dusts and for coating calcium ammonium fertiliser. Most of the rubber manufacturers use soapstone powder as a lubricant to prevent ungalvanized rubber goods from sticking. The purer variety of steatite after calcination, industrially called 'Lava' is used in the manufacture of low loss ceramic materials required for high frequency insulations in all kinds of radio, television and related instruments. Bricks made out of crushed steatite bonded by sodium silicate are used for ssthe manufacture of furnaces in which argentiferous lead is softened before desilverising. Paper industry accounts for about 50% of the total consumption, in the domestic industry, 15% is shared by the insecticide and pesticide industries and only 3% by talcum powder manufacturers. The remaining quantity is consumed in textile, ceramics, paints, rubber, foundry facing and other industries. soapstone,soapstone powder
