Definition of Talc – The word talc is derived from the Latin word “talcum” which in turn traces its roots to the Arabic and Persian “talq” which was used to denote a variety of minerals like talc and mica.
Talc is the softest of all minerals. It belongs to a category of minerals known as “clay minerals”.
Talc powder ingredients
Talc is composed of hydrated magnesium silicate. The chemical formula of talc is Mg3Si4O10(OH)2.
Almost everyone on Earth knows Talc. It is the mineral that is crushed to make baby powder or talcum powder. Sometimes it is also mixed with corn starch to make talcum powder.
What does talc powder do to your skin?
The composition and structure of Talc gives it properties like the ability to absorb moisture, oils and odor. It also has the ability to make skin cells contract (astringent). These properties make it an important ingredient in cosmetic and first aid powders.
Talc powder uses in industry
Surprisingly, this very visible use of Talc in the manufacture of talcum powder accounts for only a small percentage of its consumption around the world. The unseen uses are many and significantly larger by volume. These include industries as varied as ceramics, rubber, paint, plastics and many more.
Is Talc a Lubricant?
The sheet like structure of talc and its property of perfectly cleaving along the planes of the sheets, which are very weakly held together, makes it extremely soft; gives it a greasy or soapy texture; and also makes it useful as a lubricant under very high temperatures.
Talc can be green, white, grey or colorless. However, when finally crushed to suit industrial usage it becomes mainly white or off-white with a pearly luster.
Uses of Talc:
Apart from its use in the manufacture of talcum powder, baby powder and first aid powders, the unique properties of Talcum make it an important raw material in several industries.
In fact, we use products that have Talc in them on a daily basis but we are seldom aware that Talc plays an important role in the composition and manufacture of these products.
Talc in plastics:
By far, the largest use of Talc worldwide is in plastics. Several products like polypropylene, vinyl, nylon and polyester have talc in them as a filler because talc helps to increase their stiffness. Talc also increases their resistance to heat and helps to mitigate shrinkage.
Because of its softness Talc reduces the wear and tear of equipment used to extrude plastics as compared to other mineral fillers which are harder.
Talc in Ceramics:
Talc is extensively used in the manufacture of ceramics, tiles, sanitary ware, pottery and dinnerware because it has a beneficial effect on the firing behavior and the strength of the final product.
Talc in paints:
Paints and coatings are basically a liquid in which mineral particles are suspended. When the liquid evaporates the particles adhere to the surface.
Talc which is used as a filler and extender, because of its plate like shape, aids the suspension of the solids in the paint cans. It also enhances the ability of the paint to stick to the surfaces without sagging. Since crushed Talc is mainly of a bright white color, it helps to make the paint brighter and whiter.
Talc in Paper industry:
The usefulness of Talc in the manufacture of Paper is very similar to its use in Paints. Talc is used as a filler in the base pulp which in turn is rolled out in thin sheets to create paper. Talc helps to fill the gaps between the fibers of wood and rags and other organic materials which make up the pulp. In addition to this, Talc improves the brightness, whiteness, the opacity and the ability of the paper to absorb ink.
Major Talc producing Countries in the World:
China, South Korea, India, United States, Finland, Brazil, France, and Japan are the major producers of Talc in the world.
India produces about 11% of the global output of Talc.
