Description

Zinc(+2) Cation Carbonate is a fundamental inorganic salt, also known as zinc carbonate basic, with the CAS registry number 10476-83-2. This compound serves as a versatile and critical source of zinc ions for a wide range of industrial and manufacturing processes. It is essential for industries requiring a reliable and consistent zinc precursor, particularly in the production of ceramics, pigments, and nutritional supplements. Its utility extends to applications in rubber compounding, agricultural micronutrients, and personal care products.

Application

• Ceramic and Glass Manufacturing: Acts as a flux and opacifier in glazes and frits, contributing to whiteness and thermal stability.
• Pigment and Filler Production: Used in the synthesis of zinc oxide and as a white pigment/filler in paints, coatings, and plastics.
• Nutritional Supplements and Animal Feed: Serves as a vital zinc source in mineral premixes and feed additives to prevent deficiencies.
• Rubber and Latex Industry: Functions as an activator in vulcanization processes and as a reinforcing agent.
• Personal Care Products: Utilized as an absorbent and mild astringent in cosmetics, deodorants, and baby powders.
• Agricultural Micronutrients: Incorporated into fertilizers and foliar sprays to correct zinc deficiencies in crops.
• Chemical Synthesis: A key starting material for producing other zinc salts, catalysts, and specialty chemicals.
• Flame Retardants and Smoke Suppressants: Used in polymer formulations to enhance fire resistance.

Quality Control

Our Zinc(+2) Cation Carbonate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for zinc content, impurity profiles, and physical properties. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, heavy metal limits, and loss on drying. We can supply grades compliant with various industrial standards, including technical, feed, and cosmetic grades, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Store away from strong acids.
