Product type
Zinc oxide is an inorganic compound that appears as a white powder or crystalline solid. It is produced by the oxidation of zinc and is known for its high thermal stability and low solubility in water. This compound is widely used in various industrial applications due to its unique properties, including its ability to act as a pigment, a UV filter, and a catalyst in chemical reactions.
| Chemical formula | ZnO |
| Purity | Typically 95% to 99.9% |
| Particle size | Nanoparticles to micrometer range |
| Melting point | 1975°C |
| Density | 5.61 g/cm³ |
When selecting zinc oxide, buyers should consider the required purity level, as this can impact the performance in specific applications. It's important to specify the desired particle size, especially for applications in cosmetics or pharmaceuticals where finer particles may be needed. Additionally, buyers should inquire about certifications and compliance with industry standards relevant to their use case, as well as the quantity needed for their projects.
