Ground Calcium Carbonate

Specifications Products : Ground Calcium Carbonate Use ; Industrial Use Color : White Form : Powder Packing Type : Plastic Bags Packing Size : 50kgs Purity : 90-99% Whiteness : 88 - 96% Ground Calcium Carbonate Calcium Carbonate is composed of the crystalline mineral, calcite, which occurs naturally in the form of chalk, marble, dolomite or lime stone. Chalk is formed by shells of Nanofossils that is a fine micro crystalline material. Other forms of calcite are also of biogenic origin but more compacted than chalk. Marble deposits are limestone changed by crystallization under conditions of extreme heat and pressure. In some cases, is process yields pure marble of exceptional whiteness. Good quality marble and dolomite deposits are available in the state of Rajasthan (India). High quality stones are manually selected at the mines and after its purity tests, these are sent to the processing centre. During the process the stones are washed to remove impurities. These stones are crushed and grinded as per the customers' requirement. The powder is further processed to micronize varying micron size up to 5 microns top cut. After micronizing it is subject to a process of unique surface coating with fatty acids or suitable coupling agents. The coated products become hydrophobic which increase the compatibility with polymers and other organic based Additives. The processing techniques at PEEKAY MINERALS ensures consistent quality, control of top-cut and average particle size and freedom from impurities at pocket friendly costs. On demand at PKM coated Ground Calcium Carbonate is made available. Coating with Stearic acid or Titanates coupling agent is being carried as per choice of end users.
