We are offering calcite powder. Calcium carbonate, or caco3, is one of the most useful and versatile materials known to man. it is extremely common and found throughout the world in sedimentary, metamorphic and igneous rocks. Some geologists consider it to be a ubiquitous mineral one that is found everywhere. It comprises more than 4% of the earths crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. The properties of calcite make it one of the most widely used minerals. It is used as a construction material, abrasive, agricultural soil treatment, construction aggregate, pigment, pharmaceutical, acid neutralization, sorbents, monuments & statuary and more. It has more uses than almost any other mineral. Calcite has a hardness of 3.0 on the mohs scale and that makes it suitable as a low-hardness abrasive.Calcium carbonate as chalk has been used as a writing tool for over 10, 000 years and is a fine, microcrystalline material. As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is re-crystallized under conditions of high temperature and pressure.

We are offering dolomite powder. Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of camg(co3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is rarely found in modern sedimentary environments but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of feet thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were post-depositionally altered by magnesium-rich pore water to form dolomite. Dolomite has a mohs hardness of 3 12 to 4 and is sometimes found in rhombohedral crystals with curved faces. Dolomite produces a very weak reaction to cold, dilute hydrochloric acid; however, if the acid is warm or if the dolomite is powdered a much stronger acid reaction will be observed. (powdered dolomite can easily be produced by scratching it on a streak plate.).Dolomite is very similar to the mineral calcite. Calcite is composed of calcium carbonate (caco3) while dolomite is a calcium magnesium carbonate (camg(co3)2). These two minerals are one of the most common pairs to present a mineral identification challenge in the field or classroom. The best way to tell these minerals apart is to consider their hardness and acid reaction. Calcite has a hardness of 3 while dolomite is slightly harder at 3 12 to 4. Calcite is also strongly reactive with cold hydrochloric acid, while dolomite will effervesce weakly with cold hydrochloric acid.

We are offering talc powder.Talcsoapstone powder of superfine & ultra-fine particle size. Our talc grades are highly lamellar, homogenous with a whiteness and brightness of >90%.

We are offering barite powder. Barite or barytes is chemically naturally occurring barium sulphate (baso4) with nodular particle structure. It receives its name from the greek word barys which means heavy. this name is in response to barites high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical and manufacturing uses. barite also serves as the principal ore of barium. Supplied in super snow white (ssw) and off color and it is a fine flow powder. It is insoluble in water and has low oil absorption. This coupled with strong crystalline structure and high refractive index helps it to impart strength.Barite is generally easy to identify. It is one of just a few nonmetallic minerals with a specific gravity of four or higher. Combine that with its low mohs hardness (2.5 to 3.5) and its three directions of right angle cleavage, and the mineral can usually be reliably identified with just three observations.Most barite produced is used as a weighting agent in drilling muds. These high-density muds are pumped down the drill stem, exit through the cutting bit and return to the surface between the drill stem and the wall of the well. This flow of fluid does two things: 1) it cools the drill bit; and, 2) the high-density barite mud suspends the rock cuttings produced by the drill and carries them up to the surface.Barite is also used as a pigment in paints and as a weighted filler for paper, cloth and rubber. The paper used to make some playing cards has barite packed between the paper fibers. This gives the paper a very high density that allows the cards to be dealt easily to players around a card table. Barite is used as a weighting filler in rubber to make anti-sail mud flaps for trucks.Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding.
