Supply calcite calcite calcite block

Calcite is a carbonate mineral that natural calcium carbonate is the most common. Therefore, calcite is a widely distributed minerals. Calcite crystal shapes varied, which may be a collection of clusters of crystals, may be granular, massive, fibrous, bell emulsion, etc. earthy. Calcite can get a lot hitting square pieces, named party solution. Calcite color varies impurities contained therein and changes, such as when the content of iron and manganese to yellow, light red, brown and black, and so on. But more generally for white or colorless. Colorless transparent calcite is also called Iceland spar, calcite have such a wonderful feature is that it can be seen through the object was a double image. Thus, Iceland spar is important optical materials. Calcite is the primary mineral limestone and marble, has many uses in the production of life. We know that limestone can form caves, cave of stalactites, stalagmites and other is actually composed of calcite. Calcite is the most important characteristic of carbonate minerals, chemical composition: CaCO3, trigonal system, has full rhombohedral cleavage, shiny glass, transparent to translucent, ordinary white or colorless, contains also a lot of other colors, Streak white, hardness 3.0, specific gravity of 2.6 to 2.8, severe blistering cold dilute hydrochloric acid, pure and transparent called Iceland spar (Iceland Spar), with a strong birefringence and three sets of complete cleavage. Occurrence of calcite crystal shapes varied, the main mineral limestone, marble and beautiful it is calcite stalactites. In the spring of travertine can be deposited in the igneous rocks are usually of a secondary mineral, almond cavities in basalt flows, the inner sedimentary rocks of crack often made of calcite veinlets filling, or through biological role in shell or Rocks way output. Calcite use due to a birefringence, often utilized in polarizing prisms, such as in a certain way cut column, but when prism microscope, the optical detection of mineral, its quality requirements shall be: colorless, transparent, internal free bubbles or cracks, without a dual, or distort, 0.5 inches (12.5mm) cube above. Generally calcite used in chemical, cement and other industrial raw materials. Calcite in the metallurgical industry flux used in the construction industries for the production of cement, lime. Calcite powder that TSP is "heavy calcium carbonate," the abbreviation, the main ingredient is calcium carbonate, heavy calcium carbonate is also referred to as "TSP", usually used as a filler, widely used man-made floor tiles, rubber, plastics , paper, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other household chemical industry, as a filler acts to increase the volume of products, reduce production costs. The main ingredients of calcite CaCO3, the theoretical chemical composition: CaO: 56.03%, CO2: 43.97%, often MgO, FeO, MnO, etc. isomorphous instead. Calcite generally white, milky white or colorless, 2.6-2.94 density, hardness 3, with shiny glass, decomposition temperature 898.6 ℃, the structure of dense, insoluble in water, soluble in acid, fewer impurities, uniform size, good processing performance , DOP oil absorption is low. Meanwhile, calcite powder can be done silicate industrial raw materials.
