Supplier: Silver stone industries have a wide range of high quality mineral powders, including ground calcium carbonate, calcite powder, talc powder, dolo talc powder, dolomite powder, low silica dolomite powder, and marble powder.
Calcium Carbonate (CaCOâ??) Powder is a naturally occurring mineral composed primarily of calcium and carbon. Known for its high purity, brightness, and low abrasiveness, calcite is widely used across various industrial sectors. It is highly valued for its ability to neutralize acids, enhance mechanical properties, and provide cost-effective filler material. Available in fine white powder with particle size ranging from 40 microns to 10 microns.
Calcite is a calcium carbonate mineral (minerals containing CO3) that is usually white. It is one of the most important minerals in the world and is extremely common. It can be found in the three main types of rocks (sedimentary, metamorphic and igneous rocks) and, in the form of marble or limestone, makes up much of the Earths crust. Calcite is one of the main minerals in limestone, marble and shells of marine species. Interestingly, calcite has more practical uses than most other minerals in the world. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. It comes in bright white color and it has nodular particle size with strong crystal structure.
The common features are as follows:
Rapid and complete dispersion
Very Low abrassion at high loading
Very low moisture content
Good compatibility with polymers and other additives
Better impact strength of polymer compound as compared to uncoated material
Applications:
As a formation bridging and filter-cake sealing agent in drilling fluids.
As a weighting material to increase the density of drilling fluids, to control downhole pressures.
As an extender in paints, especially in matte emulsion paints.
As a filler in plastics (example - 15 to 20% loading of chalk in PVC drain pipe) as well as thermosetting resins.
In a wide range of trade and DIY adhesives, sealants, and decorating fillers.
In setting stained glass windows, along with putty.
As a resist to prevent glass from sticking to kiln shelves when firing glazes and paints at high temperature.
As a common ingredient for many glazes, in ceramics/glazing applications.
In the production of glossy paper, replacing kaolin.
For the purpose of purifying iron steel materials, in a blast furnace, from iron ore.
As a building material in its own right (like marble) or limestone aggregate for the purpose of road-building and construction.
For making mortar, which is used in bonding bricks, concrete blocks, stones and tiles.
As a filler material for latex gloves, as precipitated Calcium carbonate (pre-dispersed in slurry form).
As a major component of blackboard chalk.
As an inert filler for tablets and other pharmaceuticals.
As a pH corrector in swimming pools, for maintaining alkalinity buffer to offset the acidic properties of the disinfectant agent.
In the production of toothpaste.

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.
