High purity calcium carbonate

Our high purity calcium carbonate, whose content is not less than 99.5%, is widely used in electronic industry and Chemical reagent. The content of Pb, Mg and metal items is low enough to meet the international standards. Our high-purity calcium carbonate, low in metal impurity, is synthesized by chemical materials, which could meet the requirements of high insulation character as filler. The content of CaCO3 is not less than 99.5% with low content of metal ions, superior to the specifications of Chemical Pure CaCO3 (98.5%) and Analytically Pure CaCO3 (99.0%). It can be widely used in the fields of ceramic, electronic industry, film capacitive material, optics glass, spectrum agent.
