High Purity Silica Micro Powder

High-purity silica micro powder

High-purity silica micro powder is an inorganic non-metallic functional powder material, mainly composed of SiO₂. The product is refined from high-purity crystalline silicon or natural high-purity quartz through multiple processes including crushing, purification, grinding, and grading. The product possesses excellent properties such as high purity, controllable particle size, الاستقرار الكيميائي الجيد, مقاومة درجات الحرارة العالية, low expansion, and high insulation.

ميزات المنتج

1. High Purity, Low Impurity Content

Product purity can reach 99.7%~99.999% or higher, with extremely low levels of harmful impurities such as Fe₂O₃ and Al₂O₃. Iron content in some electronic-grade products can be controlled below 0.002%, meeting the stringent purity requirements of high-precision fields.

2. Controllable Particle Size, Uniform Distribution

Through a fine classification process, precise control of particle size from submicron to micron is achieved. Narrow particle size distribution and good dispersibility meet the diverse particle size requirements of different applications.

3. Excellent Chemical Stability

SiO₂ material is chemically inert, resistant to acid and alkali corrosion (except hydrofluoric acid), insoluble in water, and stable in various organic and inorganic systems.

4. High Temperature Resistance, Low Thermal Expansion

With a melting point of approximately 1700℃ and an extremely low coefficient of thermal expansion, it exhibits excellent dimensional stability at high temperatures, making it suitable for composite materials and refractory products under high-temperature conditions.

5. High Insulation

It possesses excellent electrical insulation properties, making it a key functional filler in electronic packaging materials, insulating materials, and cable fillers.

6. Good Filling and Reinforcing Effects

As a functional filler, it effectively improves the strength, abrasion resistance, aging resistance, and thixotropic properties of plastics, rubber, and coatings.

الأسئلة المتداولة (التعليمات)

1. What purity level can this product achieve?

Depending on the product grade, purity ranges from ≥99.7% (industrial grade high purity) to ≥99.999% (electronic grade). Products with appropriate purity can be selected based on specific application requirements.

2. In which industries is this product most widely used?

Applications cover electronic packaging (EMC molding compounds), specialty ceramics, coatings, rubber, plastics, and specialty glass industries. It can be used as a functional filler, reinforcing agent, or basic raw material.

3. How to choose the appropriate particle size?

Select according to application process requirements—micron-level ultrafine powder is generally used for electronic packaging; nano to submicron-level powders are commonly used for coatings and rubber; ceramics and refractory materials require powders of appropriate mesh size depending on the molding process. Our company supports customized particle sizes; please contact our sales engineers for specific details.

4. How should the product be stored? What is its shelf life?

It is recommended to store in a sealed container under cool, dry conditions to prevent moisture and clumping. The shelf life under sealed, dry conditions is 24 months from the date of production.

5. What safety precautions should be taken during handling and use?

It is recommended to wear a dust mask and protective gloves during handling to avoid inhaling dust. Handle with care during loading and unloading to prevent breakage of the bag. The Safety Data Sheet (SDS) is provided with the product; it is recommended to read it carefully before use.
