Publish Time: 2025-06-25
In modern industrial production, calcined zinc oxide, as an important inorganic functional material, is widely used in rubber, ceramics, glass, coatings, electronic devices, medicine and other fields due to its excellent thermal stability, chemical activity, antibacterial properties and optical properties. Zinc oxide after high-temperature calcination not only improves purity and crystallinity, but also enhances its physical and chemical properties, making it an indispensable key raw material in many high-end manufacturing processes.
The biggest advantage of calcined zinc oxide lies in its excellent thermal stability and chemical inertness. The high-temperature calcination process removes impurities, moisture and organic residues, making the crystal structure of zinc oxide more compact, more resistant to high temperatures, and able to maintain a stable state under high temperature conditions. This feature makes it particularly suitable for industrial processes such as rubber vulcanization accelerators, ceramic glazes, and glass additives that require high-temperature treatment, effectively improving the quality and service life of the final product.
In terms of functionality, calcined zinc oxide exhibits good antibacterial and mildew-proof and UV shielding capabilities. Due to its large specific surface area and surface activity, its nano-scale particle structure can be used as an efficient antibacterial agent in coatings, plastics, textiles and other fields to inhibit the growth of bacteria and fungi and extend the service life of products. At the same time, it has a strong absorption and scattering effect on ultraviolet rays, and is often used in sunscreen cosmetics, outdoor building materials and functional coatings to protect the substrate from ultraviolet aging.
In addition, calcined zinc oxide also has a wide range of application potential in electrical properties. In the electronics industry, it can be used to manufacture electronic components such as varistors, gas sensors, and phosphors, and is favored for its good conductivity regulation ability and response sensitivity. Especially in new energy equipment such as solar panels and LED lighting systems, calcined zinc oxide, as a transparent conductive film material, helps to improve the photoelectric conversion efficiency and promote the development of green energy technology.
Environmental safety is also one of the important advantages of calcined zinc oxide. As a non-toxic, odorless and environmentally friendly functional material, calcined zinc oxide does not release harmful substances during production and application, and complies with a number of international environmental standards such as RoHS and REACH. Compared with some heavy metal additives, calcined zinc oxide has less impact on human health and the ecological environment, and is suitable for use in food packaging, children's toys, medical devices and other fields with high safety requirements.
Finally, calcined zinc oxide has good processing adaptability and cost-effectiveness. It can be well combined with a variety of resins, rubbers, and ceramic matrices, and can be surface modified according to different application requirements to improve dispersibility and compatibility. At the same time, with the continuous optimization of production processes, the cost-effectiveness of calcined zinc oxide is increasing, providing various companies with more competitive raw material options.
Calcined zinc oxide is becoming a key functional material in many industries due to its high thermal stability, excellent antibacterial properties, UV shielding ability, electrical functionality, green environmental protection and good processing adaptability. It not only expands the application boundaries of zinc oxide, but also provides a solid foundation for promoting the development of new material technology and industrial upgrading.
