Product Overview:
The ultra-fine industrial-grade high-temperature-resistant fused silica micro-powder is a high-purity silicon dioxide (SiO) powder material prepared through a high-temperature melting process. It has characteristics such as ultra-fine particle size, high-temperature resistance, and excellent chemical inertness. Specifically designed for the industrial field, it is widely applied in the manufacturing of high-end materials in industries such as ceramics, electronics, metallurgy, and chemical engineering, and is suitable for the filling, reinforcement, or insulation requirements in extreme high-temperature environments.
Product Features:
Ultra-fine Particle Size: The average particle size ranges from 0.5 to 50 micrometers (customizable), with a uniform distribution, large specific surface area, and easy dispersion.
High-temperature Resistance: The melting point is as high as 1730°C, and it can withstand high temperatures of 1600°C for a long time without phase change or decomposition.
Chemical Stability: Resistant to acid and alkali corrosion, and does not react with other materials, ensuring long-term stability.
High Insulation: Low dielectric constant and high resistivity, suitable for fields such as electronic packaging and insulating coatings.
Low Coefficient of Thermal Expansion: It has good compatibility with most metals and ceramics, reducing the risk of thermal stress cracking.
Good Fluidity: The surface is specially treated, with excellent fluidity, facilitating processing and molding.
Application Fields:
Ceramic Industry: As a reinforcing filler for high-temperature sintered ceramics, it improves density and mechanical strength.
Electronic Packaging: As a filler for chip packaging and copper-clad laminates, it optimizes thermal conductivity and insulation performance.
Chemical Coatings: As an additive for high-temperature-resistant coatings, it enhances the wear resistance and corrosion resistance of the coating.
Metallurgical Casting: As a release agent for precision casting or an additive for refractory materials.
Composite Materials: As a high-performance reinforcing agent for plastics and rubbers, it improves heat resistance.
Refractory Materials: As a high-temperature-resistant component for the inner lining of kilns and castables.
Packaging and Storage:
Packaging: 25kg/bag (customizable packaging is available).
Storage: Store in a cool and dry place, avoiding a humid, high-temperature, and acid-base environment.
Precautions:
Wear a dust mask and goggles during operation to avoid inhaling dust directly.
During transportation, protect against moisture and damage, and keep away from fire sources.
