Description:
Zinc carbonate basic, also known as “basic zinc carbonate” or “zinc hydroxycarbonate,” is a chemical compound with the molecular formula Zn5(OH)6(CO3)2. It is a white, insoluble powder that occurs naturally as the mineral “hydrozincite.” Basic zinc carbonate is commonly used as a pigment in paints, rubber products, and ceramics. It is also used as a mildewcide, a fire retardant, and in the production of other zinc compounds. Additionally, it has applications in the pharmaceutical and cosmetic industries. The compound is formed through the reaction of zinc salts with alkaline substances, resulting in the precipitation of the basic carbonate.
Storage:
In 25kg plastic bag. A shelf life of 2 years is expected if material is stored in sealed original packaging. Keep container tightly closed in a dry and well-ventilated place. Store in cool place.
