Silicon Dioxide Powder for Sale: Meeting Industrial Demands
The global market for silicon dioxide powder is projected to reach $7.3 billion by 2028, driven by its critical role in semiconductors, pharmaceuticals, and coatings. As manufacturers seek high-purity SiO₂ powders (≥99.9%), suppliers must balance particle size consistency (10-50nm range) with scalable production. Recent data shows 68% of purchasers prioritize vendors offering both standard and customized granulometry options.
Technical Superiority in Material Engineering
Our silicon dioxide powder achieves 99.99% purity through advanced hydrothermal synthesis, outperforming conventional flame pyrolysis methods. Key parameters include:
- Surface area: 300-400 m²/g (BET measurement)
- Tap density: 0.08-0.12 g/cm³
- Thermal stability: Up to 1,200°C
XRD analysis confirms amorphous structure (98% non-crystalline content), crucial for optical applications requiring low light scattering.

FAQS on silicon dioxide powder for sale
Q: Where can I find silicon dioxide powder for sale?
A: Silicon dioxide powder is available through chemical suppliers, industrial material distributors, and online platforms like Amazon or Alibaba. Ensure the supplier provides certifications for purity and safety.
Q: What are the common uses of silicon dioxide powder?
A: Silicon dioxide powder is used in pharmaceuticals, food additives, cosmetics, and electronics manufacturing. It acts as an anti-caking agent, filler, or insulator in these applications.
Q: How is silicon dioxide converted into silicon?
A: Silicon dioxide is reduced to silicon through carbothermal reduction in high-temperature furnaces. This process involves reacting SiO₂ with carbon to produce pure silicon and carbon dioxide gas.
Q: Is silicon dioxide powder safe for industrial use?
A: Yes, but proper safety measures like gloves, masks, and ventilation are required. Prolonged inhalation of fine particles may pose respiratory risks.
Q: What factors affect the price of silicon dioxide powder?
A: Pricing depends on purity grade, particle size, packaging, and order volume. Specialty grades for electronics or pharmaceuticals typically cost more than industrial-grade powder.
