Talc is a metamorphic mineral which can be found in rocks, in foliated masses and sometimes in veins. One can describe talc as Soapstone because of its softness and greasiness. Talc’s structure is similar to micas and clay minerals. It mostly found in the form of magnesium silicates though it covers a wide range of primary rocks and minerals. It is sheet silicate basically.
Talc is a diverse mineral because of its numerous properties. Its layered form gives it a softness, anti-sticking, anti-caking and barrier effect. It has electro-insulating properties which make it useful in electronic industries to make things like wires and cables. Because of its inertness it can be used in pesticides, pharmaceutical, premixes and cosmetics. It has a long chain of characteristics.
Talc is a metamorphic rock usually composed of hydrated magnesium silicate mineral, whose chemical formula is Mg3Si4O10 (OH) 2. It is basically a mineral which belongs to the class of silicates. It is a sheet silicate which means that it is structurally similar to micas and clay minerals. It is a translucent mineral with a pearly luster.
Properties of Talc :
Mineral Talc can be crushed into a white powder which is widely known as Talcum Powder or Baby Powder. It is a rock known as steatite or soapstone and we convert it into a fine powder used for cosmetics item.
It is so soft that one can scratch it with a fingernail. Great care is taken during the mining process to avoid contaminating the talc with other rock materials. Our Mineral Mines consist of very good quality of Talc Rock.
The softness and waxy feel are useful properties that make the identification of the mineral quite easy.
Talc in its pure form appears in white. If the other substances are added in the talc it becomes pink or gray accordingly.
It is highly resistance to heat and electricity.
It is also called anti-sticking agent because it prevents two materials from sticking together.
It does not react with active ingredients.
It has the property of not generating bacterial growth.
It is very smooth and can be used in products that require suppleness and smoothness. Thus it is very important industrial material.
It occurs commonly in thin layers, but is also found in irregular large granular, finely granular, or cryptocrystalline masses. Soapstone, or steatite, is an extensive, granular form of talc. One of the remarkable features of talc is its simple, almost constant composition; Unlike other silicates, even closely related ones, talc appears to be unable to accept iron or aluminum into its structure to form chemical-replacement series, even though an iron of talc is known, and the structurally related chlorite forms at least a partial series between iron and magnesium end-members. Talc is distinguishable from pyrophyllite chemically and optically. For detailed physical properties, see silicate mineral (table). French chalk is a fine-grained variety of talc rock. Talc is usually related with chlorite, serpentine, Dolomite, and other metamorphic rocks; it is basically a secondary mineral formed by the modification of other magnesium silicates.
