Physical and chemical properties

• Stability: High-purity quartz sand is a neutral inorganic filler, free of crystalline water, and does not participate in the chemical reactions of the filled material, offering an extremely high level of chemical stability.Hydrofluoric AcidNot soluble in any other acid.
• 
  
• High-temperature resistance: Can withstand temperatures up to 1200℃ or higher, and is a transparent refractory material.
• 
  
• Coefficient of Thermal Expansion: Low coefficient, only 5.5×10^-7/℃ between 0~1000℃.
• 
  
• Transparency: Excellent light transmission, allowing UV, visible light, and infrared rays to pass through effectively.
• 
  
• Electrical Insulation: Excellent electrical insulation properties, with a resistivity of 10^18 Ω/cm at 20°C and an insulation strength of 250 kV/cm.
