Calcite is a natural crystal that has high birefringence and wide spectral transmission and available in reasonably sized rhombus. Its Distinct features are as under:1. Rapid and complete dispersion 2. Very Low abbrassion at high loading 3. Very low moisture content 4. Good compatibility with polymers and other
Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.

1.4" Chrysocolla on Quartz and Calcite - Tentadora Mine, Peru. This is a colorful association of botryoidal chrysocolla that formed over quartz and calcite. It was collected from the Tentadora Mine in the Castrovirreyna Province of Peru. This locale is renown for these .
A number of different calcite crystal forms are possible: scalenohedral, rhombohedral and prismatic. Less common is aragonite, which has a discrete or clustered needle orthorhombic crystal structure. Rare and generally unstable is the vaterite calcium carbonate mineral.
Pure calcium hydroxide paste has a high pH (approximately 12.5-12.8) and is classified chemically as a strong base. Its main actions are achieved through the ionic dissociation of Ca (2+) and OH (-) ions and their effect on vital tissues, the induction of hard-tissue deposition and the antibacterial properties.
Type 1 is associated with granular subhedral crystal fabrics and typically exhibit relatively large average pore throat radii (ca. 0.7 mm) as well as high porosity (> 20%) and permeability (1-20 mD).
