High Purity Glass Powder

High Purity Glass Powder is a finely processed, ultra-clean recycled or virgin glass material engineered for applications requiring exceptional chemical stability, whiteness, and performance consistency. Produced using advanced crushing, grinding, washing, and magnetic separation systems, this powder offers high silica content (>99% in virgin grades) and extremely low impurities, making it suitable for demanding industrial, scientific, and decorative applications.

Premium high purity glass powder made from ultra-clean recycled glass. High silica, low contaminants, and consistent fineness for concrete, ceramics, coatings, terrazzo, filtration, and industrial fillers.

Key Features

• High Silica Content – Typically 70–74% for recycled grades; 99%+ for virgin ultra-pure grades.
• Ultra-Low Impurities – Controlled levels of metals, ceramics, organics, and other contaminants.
• Consistent Particle Size – Available in micro-fine, fine, and custom grades.
• High Chemical Stability – Non-reactive, non-hazardous, and thermally stable.
• Excellent Whiteness – Suitable for premium décor and high-end industrial uses.
• Eco-Friendly – Reduces raw material demand and supports circular-economy recycling.
