Limestone (CaCO₃)

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral, CaCO₃. It is hydrophobic and is produced by crushing, grinding, precipitation, and classifying high purity, white, and calcite limestone. Purities available from 98% to 99.9%
Detailed Particle Size Information

Precipitated CaCO₃ powder granulations are available down to nanoparticles as fine as 30 nanometers

Grades Offered

Pharmaceutical (USP) grade
Food (FCC) grade
Electronic grade
Optical grade

Typical Applications

Limestone has a wide variety of uses including in plastics, rubber, coatings, inks, adhesives, and soil conditioners. It is used in building products as a plastic filler, ceramic flux, and asphalt filler.
