At NINGBO INNO PHARMCHEM CO.,LTD., we provide a comprehensive range of chemical raw materials, including the widely used zinc oxide powder. To fully appreciate its utility, it’s important to understand its fundamental chemical identity and properties. Zinc oxide is an inorganic compound that holds significant importance across diverse sectors due to its unique characteristics.

The chemical formula for zinc oxide is ZnO. This formula indicates that each molecule of zinc oxide consists of one zinc atom and one oxygen atom. This simple yet effective composition gives rise to a compound with remarkable properties. A crucial identifier for any chemical substance is its CAS Registry Number. For zinc oxide, the CAS number is 1314-13-2. This unique identifier is essential for regulatory compliance, safety data sheets, and clear communication within the chemical industry. When you buy zinc oxide powder, confirming its CAS number ensures you are receiving the correct and intended material.

As previously highlighted, zinc oxide powder typically appears as a fine white powder. Its melting point is notably high, occurring at 1975°C, which speaks to its thermal stability. This high thermal resistance makes it suitable for applications exposed to elevated temperatures. Its density is approximately 5.6 g/cm³, and it has a refractive index ranging from 2.008 to 2.029, which influences its performance as a pigment and UV absorber.

In terms of solubility, zinc oxide is described as extremely slightly soluble in water. This low solubility is advantageous in applications where it needs to remain stable and functional in aqueous environments, such as in certain types of coatings or medical preparations where controlled release is desired.

Understanding these properties, including the precise chemical formula and CAS number, is vital for researchers, formulators, and manufacturers. Whether you are looking for 99.8% zinc oxide powder for sensitive cosmetic applications or require it as a reinforcing agent for rubber, knowing its fundamental chemical identity ensures you are sourcing the right material. The zinc oxide price can vary based on purity and grade, making the CAS number a reliable point of reference.
