High Purity Zinc Oxide 99.9% PowderHigh Purity Zinc Oxide (ZnO) with a purity level of 99.9% is a specialized form of zinc oxide renowned for its exceptional quality and minimal impurities. This substance is typically produced through meticulous purification processes to ensure its high degree of purity. Here is a detailed description of this remarkable material:

Appearance: High purity ZnO is a fine, white to off-white powder. Its appearance is characterized by its remarkable brightness and homogeneity.

Purity: The purity level of 99.9% signifies that this zinc oxide is nearly devoid of impurities, with only minute traces of other elements present. This high purity is achieved through precise manufacturing techniques and stringent quality control.

Particle Size: It comprises nanoparticles with an average particle size of less than 100 nanometers (nm). This fine particle size allows for uniform dispersion in various applications and contributes to its excellent performance characteristics.

Chemical Composition: Its chemical formula is ZnO, indicating that it consists solely of zinc and oxygen atoms. The absence of significant contaminants, such as heavy metals, ensures its safety and suitability for a wide range of applications.

Bulk Density: High purity ZnO typically has a bulk density of at least 0.6 grams per cubic centimeter (g/cm³). This density can vary slightly depending on the specific manufacturing process.

Moisture Content: The moisture content is minimal, usually less than 0.5%, which makes it suitable for applications where moisture sensitivity is a concern.

Physical Properties: It exhibits excellent optical properties, with high whiteness and tint-reducing power, making it ideal for use in pigments, paints, and coatings.

Chemical Properties: This zinc oxide is insoluble in water and remains stable under normal environmental conditions. It can, however, react with acids and alkalies.

Applications: High purity ZnO with a 99.9% purity level finds widespread use in various industries, including:

  • Cosmetics and Personal Care: It is utilized in sunscreens, skincare products, and cosmetics due to its UV-blocking properties and safety.

  • Pharmaceuticals: It meets stringent pharmaceutical standards and is used in medicinal formulations.

  • Electronics: In the electronics industry, it is employed in the manufacture of semiconductors and electronic components.

  • Ceramics: Its high purity contributes to improved mechanical strength and thermal stability in ceramic products.

  • Environmental and Catalytic Applications: Its photocatalytic properties are harnessed for water purification and air pollution control.

Storage: It should be stored in a dry, well-ventilated area away from moisture and direct sunlight to maintain its purity and properties over time.
