5 FAQs of High purity Fused silica Silicon oxide SiO2 quartz powder 99%-99.999%

What is high-purity fused silica (SiO2) quartz powder? High-purity fused silica quartz powder is a finely ground form of silicon dioxide (SiO2) processed to remove impurities, achieving purity levels between 99% and 99.999%. It is produced by melting high-grade quartz crystals at extreme temperatures, followed by milling and purification. The material is known for its exceptional thermal stability, chemical inertness, and low thermal expansion, making it ideal for advanced industrial and technological applications.

What are the primary applications of high-purity SiO2 quartz powder? This material is widely used in semiconductors, solar panels, optical fibers, and LED lighting due to its dielectric properties and transparency. It is also used in high-temperature coatings, ceramics, epoxy resins, and precision molds. In construction, it enhances durability in cement and refractory materials. Higher purity grades (99.99% to 99.999%) are critical for electronics, optics, and aerospace components.

How does purity level affect performance? Higher purity (99.99%-99.999%) ensures minimal contaminants like alkali metals or heavy metals, which can interfere with electrical or optical performance in sensitive applications. Lower grades (99%-99.9%) are suitable for less demanding uses like construction or coatings. The choice depends on the required thermal, electrical, or chemical resistance.

How is high-purity fused silica quartz powder manufactured? The process involves melting natural quartz crystals at over 2000°C, followed by rapid cooling to create amorphous fused silica. The material is then milled into fine powder and purified via acid leaching, magnetic separation, or advanced filtration. Particle size is controlled through grading or classification to meet application-specific needs.

What precautions are needed for handling and storage? While non-toxic, the fine powder can pose inhalation risks. Use protective masks and gloves. Store in airtight, moisture-proof containers in a dry, cool environment to prevent clumping or contamination. Avoid contact with strong acids or alkalis unless specified for intended use. Ensure compliance with local safety regulations for silica-containing materials.
