Advantage:
Silica powder boasts exceptional purity, ensuring that it meets stringent quality standards. The absence of impurities enhances its performance and makes it suitable for applications where purity is critical, such as in the manufacturing of optical components.
The high whiteness of silica powder is advantageous in industries where a bright and clear appearance is essential. This property is particularly valuable in the production of optical glass and quartz glass, where transparency and aesthetics are key factors.
The superfine size of silica powder contributes to its versatility and effectiveness in various processes. Fine powder ensures a more uniform distribution and better integration in different materials, making it suitable for applications that require precision and consistency.
Silica powder with a centered size distribution provides uniformity in particle size, resulting in improved handling and processing. This characteristic is crucial in applications like crucible manufacturing, where consistent material properties are vital for reliable performance.
The low electric conductivity of silica powder is beneficial in applications where electrical insulation is required. This property makes it ideal for use in the production of insulating materials and components.
The extremely low radioactivity content ensures that the silica powder meets safety standards, making it suitable for use in sensitive applications. This feature is particularly important in industries such as nuclear and electronics, where low radioactivity is a critical requirement.
