Overview
Basic Zinc Carbonate, chemically known as Zn5(CO3)2(OH)6, is an inorganic compound derived from zinc oxide and carbon dioxide. It is a white, crystalline powder with no discernible odor. The compound is primarily synthesized for industrial applications due to its stability and versatile chemical properties. Historically, Basic Zinc Carbonate has been used in medicinal preparations, though its modern applications are predominantly industrial. Its ability to act as a flame retardant and vulcanizing agent makes it valuable in multiple sectors, including rubber manufacturing and ceramics.
Physical and Chemical Properties
Basic Zinc Carbonate is characterized by its high density (4.4 g/cm³) and insolubility in water. It decomposes at approximately 300°C, releasing carbon dioxide and forming zinc oxide. The compound is stable under normal conditions but reacts with strong acids to form zinc salts. Its crystalline structure contributes to its use as a reinforcing agent in rubber products. Additionally, its ability to absorb CO2 from the air makes it useful in certain environmental applications, though this property requires careful storage to maintain product integrity.
Main Applications
The rubber industry is the largest consumer of Basic Zinc Carbonate, where it serves as an activator for vulcanization processes. It enhances the durability and elasticity of rubber products, such as tires and industrial hoses. In ceramics, it acts as a flux to lower melting temperatures during firing. The pharmaceutical industry utilizes it in topical ointments for its mild antiseptic properties. Its flame-retardant capabilities are leveraged in plastics and textiles to improve fire resistance.
Safety and Storage
While Basic Zinc Carbonate is non-toxic, prolonged exposure to dust may cause respiratory irritation. Workers should wear masks, gloves, and goggles when handling the powder. Storage requires a dry environment to prevent moisture absorption and CO2 uptake. Containers must be sealed tightly and placed away from acidic substances to avoid chemical reactions. Spills should be cleaned promptly with damp cloths to minimize dust dispersion.
B2B Procurement Guide
When sourcing Basic Zinc Carbonate, prioritize suppliers with ISO or REACH certifications to ensure quality and regulatory compliance. Key specifications include purity (≥98%), particle size distribution (typically 1–10 microns), and absence of heavy metal contaminants. Bulk pricing varies by order volume and supplier location. Request samples to test compatibility with your application. Long-term contracts may offer cost advantages for high-volume buyers.
