5 FAQs of High Purity 300nm Spherical Quartz Powder Nano Silica Powder At Lowest

What is High Purity 300nm Spherical Quartz Powder Nano Silica Powder?
High Purity 300nm Spherical Quartz Powder is a nanomaterial composed of spherical silica particles with an average diameter of 300 nanometers. It is synthesized using advanced processes to ensure high purity (typically ≥99.9%), uniform particle size, and excellent sphericity. This powder is widely used in electronics, coatings, ceramics, and composite materials due to its thermal stability, low thermal expansion, and enhanced mechanical properties.

Why is the 300nm particle size significant?
The 300nm size optimizes surface area-to-volume ratio, improving reactivity and dispersion in matrices while maintaining flowability. This size is ideal for applications requiring precise filling or coating, such as semiconductor packaging, optical fibers, and advanced polymers. It balances performance in viscosity control, light diffusion, and mechanical reinforcement without compromising processability.

What purity levels are guaranteed?
The product boasts a purity of ≥99.9%, with trace metal impurities (e.g., Fe, Al, Na) minimized to ppm levels. This is achieved through refined purification techniques like acid leaching and high-temperature calcination. High purity ensures reliability in sensitive applications like microelectronics, where contaminants can degrade performance or cause device failure.

How is this silica powder used in electronics?
In electronics, it serves as a filler in epoxy molding compounds for semiconductor encapsulation, enhancing thermal conductivity and reducing stress. It’s also used in printed circuit boards, LED encapsulants, and thermal interface materials. Its spherical shape reduces friction during injection molding, ensuring smooth processing and uniform distribution in composites.

What safety precautions are required during handling?
Though non-toxic, inhalation of nano-silica powder should be avoided. Use PPE (masks, gloves, goggles) and work in well-ventilated areas. Store in airtight containers away from moisture and high temperatures. Follow local regulations for disposal. The material is chemically inert but may cause irritation if exposed to eyes or skin—rinse thoroughly with water if contact occurs.
