A Comprehensive Guide to the Five Main Types of Quartz Sand

Quartz sand, derived from crushed quartzite, is a vital industrial material known for its high refractoriness, chemical stability, and versatility. This guide explores the five primary types of quartz sand, detailing their composition, production processes, and key applications across various industries.

1. Ordinary Quartz Sand

• Composition: SiO₂ ≥ 90–99%, Fe₂O₃ ≤ 0.06–0.02%

• Refractory Temperature: 1750°C

• Production Process: Crushing, washing, drying, and screening of natural quartz ore

• Applications: Metallurgy, glass manufacturing, enamel, cast steel, water filtration, and sandblasting

2. Refined Quartz Sand

• Composition: SiO₂ ≥ 99–99.6%, Fe₂O₃ ≤ 0.03–0.016%

• Production Process: Complex processing of high-quality quartz ore

• Particle Size: 2–2500 mesh

• Applications: High-grade glass, refractory materials, precision casting, and grinding wheels

3. High Purity Quartz Sand

• Composition: SiO₂ ≥ 99.5–99.9%, Fe₂O₃ ≤ 0.001%

• Production Process: Fine processing of selected natural quartz

• Particle Size: 0.005–1 mm

• Applications: Advanced glass, ceramics, acid-resistant concrete, electronics, and metallurgical flux

4. Fused Quartz Sand

• Properties: Excellent thermal stability, near-zero thermal expansion, high chemical purity

• Production Process: Capacitance oxidation followed by mechanical screening

• Applications: Paints, coatings, epoxy resins, electronic sealing materials, and refractories

5. Silica Flour

• Composition: Ultra-fine particles with an average size of 0.1–0.3 μm

• Production Process: Milling and grading of natural quartz

• Applications: Concrete, adhesives, plastics, rubber, tires, and coatings

Conclusion

Understanding the distinct properties and applications of each quartz sand type enables industries to select the most suitable material for their specific needs. From construction and manufacturing to high-tech electronics, quartz sand remains an indispensable resource.
