Sillimanite is a polymorph with two other minerals; kyanite and andalusite. A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals. Sillimanite is the rarest of the three trimorphs. A variety of sillimanite is called "fibrolite". It is a common fibrous massive form.
Uses for dolomite are largely similar to those for Calcium Carbonate. However, its magnesium content excludes it from foodstuffs, pharmaceuticals, the sugar industry, etc. On the other hand, magnesium, like calcium, is an important bio-element, which is of interest in agriculture and forestry. Dolomite is therefore particularly suitable for the rehabilitation of over-acidified lands and waters.
Calcium carbonate has many natural uses as well as commercial ones. A commercial use of calcium carbonate is its use in antacids, as filler in the paper industry, used in decorating and construction as well as its heated form, marble. Calcium Carbonate is found in many grocery store products such as backing powder, dry-mix dessert mixes, dough, plastic, and wine
Silica is a specialist semiconductor distribution business offering an extensive technology and product portfolio from a highly focused linecard. Silica gel is used in various fields of our daily life as high adsorbent of high safety. Silica gel has excellent adsorption capacities at low relative humidity for keeping materials dry. Current uses of desiccant include the following ; pharmaceutical stoppers, laboratory desiccators, diagnostic and medical equipment, transformer tank breathers, drying flower, packaging during transportation and storage, gas drying and refining as well as protection of the electronic & telecommunications equipment, photographic and optical equipment, engines, clothing and leather goods, food(especially dried seaweed). Other uses of silica gel are aromatics, gas absorbent, and hydrogen, and so on.
Talc is an important industrial mineral. Its resistance to heat, electricity and acids make it an ideal surface for lab counter tops and electrical switchboards. It is also an important filler material for paints, rubber and insecticides. Even with all these uses, most people only know talc as the primary ingredient in talcum powder. Mineral specimens are not very common as it does not form very large crystals. However, it often replaces other minerals on an atom by atom basis and forms what are called pseudo morphs (false shape). The talc takes the form of the mineral it replaces. A specimen of what looks like milky quartz is quite a surprise when it not only has a soapy feel but can be scratched by a fingernail.
