Quartz glass tubes are made of fused silica, a type of quartz crystal. They are highly transparent, heat-resistant, and chemically inert . Quartz glass tubes are valued for their exceptional purity and ability to withstand high temperatures and corrosive environments, making them ideal for use in harsh conditions.
These heavy wall quartz tubing are a great way to mount coiled elements in a oven or kiln. Good for temperatures to 1900°F the heavy wall easily passes energy and provides a robust alternative to thin wall quartz or mullite tube mounting systems. Quartz is less sensitive to temperature shock and will withstand a water quench from 1800°F without fracturing.
Quartz glass has many excellent chemical and physical properties, making it widely used in various fields. Some key properties include:
High Temperature Resistance:
1. Softening point temperature is approximately 1730°C.
2. Can be used for long periods at 1100°C, with short-term maximum usage temperature reaching 1450°C.
Corrosion Resistance:
1. Except for hydrofluoric acid, it hardly reacts chemically with other acidic substances.
2. Acid resistance is 30 times that of ceramics and 150 times that of stainless steel.
3. Its chemical stability at high temperatures is unmatched by any other engineering material.
Physical Properties:
1. Good Thermal Stability: Low thermal expansion coefficient, capable of withstanding drastic temperature changes.
2. Good Light Transmission: Excellent light transmission performance across the entire spectrum, with visible light transmission rates above 93%.
3. Good Electrical Insulation Performance: Extremely high resistance, making it an excellent electrical insulation material.
