Heavy Calcium Powder

Introduction

Name: heavy calcium carbonate powder

Raw material: CaCO3


Description

Heavy calcium carbonate powder also called ground calcium carbonate. Calcium carbonate is a chemical compound with the chemical formula CaCO3. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. It is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 3000 mesh or above, depending on your requirement.

Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.
