Calcite Powder
It has a pivotal role in the modern industrial economy and it finds applications in various industries due to its versatility and traceability. The principal characteristics of calcite powder are transparent, high degree of purity and perfect crystalline structure. With the support of our highly experienced professionals, we export an excellent stock of Calcium Carbonate. This compound is extensively used in various industries such as paper, plastic, coating and paint. In paper & pulp, the offered Calcium Carbonate imparts high brightness and light scattering characteristic. We offer this Calcium Carbonate to clients in varied air tight packaging options in order to meet their individual requirements. These include usage in the construction and agriculture, as well as the plastics, glass, paint, paper, steel and oil industries. Calcium Carbonate is an important mineral for the healthy development of livestock. When calcium carbonate is dissolved in water saturated with carbon dioxide it produces a solution of calcium bicarbonate. Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the latter case calcium carbonate is derived from the mixture, forming a grade of product called “precipitated calcium carbonate,” or PCC. PCC has a very fine and controlled particle size, on the order of 2 microns in diameter, particularly useful in production of paper. The other primary type of industrial product is “ground calcium carbonate,” or GCC. GCC, as the name implies, involves crushing and processing limestone to create a powdery-like form graded by size and other properties for many different industrial and pharmaceutical applications.
