Quartz Glass: The Ultimate in Purity and Performance

Quartz glass—also known as fused silica—sets the benchmark for purity, thermal stability, and optical performance. Its extraordinary physical and chemical characteristics make it a mission-critical material across industries that demand absolute reliability under extreme conditions.

Key Properties of Quartz Glass

• Extreme thermal shock resistance: Maintains structural integrity under rapid temperature changes.
• Excellent UV transmission: Outstanding transparency from deep-UV through visible wavelengths.
• High electrical resistance: Ideal for high-voltage and high-frequency environments.
• Chemical inertness: Immune to corrosion from most acids and chemicals.
• Low thermal expansion: Minimizes stress, distortion, and dimensional drift.
