Talc Powder (Hydrous Magnesium Silicate) General Description:
a) A mineral which occurs naturally throughout the world. It has a platy structure
b) Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water. This is known as talc carbonation or steatization and produces a suite of rocks known as talc carbonates.
c) Talc is primarily formed via hydration and carbonation of serpentine, via the following reaction;
serpentine + carbon dioxide = talc + magnesite + water
Mg3Si2O5 (OH)4 + 3CO2 = Mg3Si4O10 (OH)2 + 3 MgCO3 + 3 H2O

Ground talc makes talcum powder. The massive variety (soapstone) is used for sinks, table tops, etc. Soapstone found a use in Babylonian days when signature cylinder seals were often carved from it.
The Egyptians also used it as a base for some of their blue faience figurines, which were then fired to fuse the glaze. California Indians also used it as sculpture material.

Uses of Soapstone Powder in Following Industries :-
Plastic Industry
consumes high quality ultra fine talc in polypropylene, polyamides, cable PVC and other plastic compounds. Talc is being increasingly used in HDPE, PP, LDPE, PVC, ABS & thermosetting compounds. It is excellent filler due to blending characteristics and thermal and electrical resistant. It is chemically inert. It provides the smooth feel to plastic surface. Due to its chemical inertness, superior electrical and thermal resistance and other properties talc imparts stiffness, hardness, tensile strength of plastic products, improves quality of their surfaces, gives them electrical, chemical and thermal resistance.
Application of Soap Stone in Paint Industries
Soap stone/French chalk/Steatite and Talc are synonymous which are used in production of decorative paints, industrial coatings, pigment pastes, primers, enamels, adhesives, putties and other products of the industry.
Paper Industry
Soap stone powder (Talc) is used in three stages of paper making-as a filler, to control pitch and stickiest and in paper coating. During the paper making process, the micro impurities can clog the paper machinery. Talc being hydrophobic absorbs these micro droplets thus controlling their stickiness and avoiding clogging. High brightness of talc leads to reduction in usage of expensive whitening agents and helps in controlling gloss of the coat. Talc gives smoothness, yellow index, porosity, and opacity to paper, improves its yellow index and reduces the deterioration of the machinery. Our grades of Talc powder are in wide range for Paper industries.
Other Uses of Soap Stone Powder (Talc)
Besides all above uses Soap stone/Talc is also widely used in Toilet Soap manufacturing, Cosmetic industries in baby talc powder, Detergent manufacturing, Dal mills (Pulses polishing), Textile, Printing Ink, Rubber industry and as a filler raw material in many chemical industries.
