Optical Fused Quartz Tube SiO2 Crystal Glass Customized Transparent Both Ends Open One Ends Closed
Description of Quartz Tube:
Quartz 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.
The Character of Quartz Tube:
1. The softening point temperature is approximately 1730°C.
2. Quartz tubes can be used for long periods at 1100°C, with short-term maximum
usage temperature reaching 1450°C.
3. Quartz tubes except for hydrofluoric acid, hardly react chemically with other
acidic substances.
4. Quartz tubes' acid resistance is 30 times that of ceramics and 150 times that of
stainless steel.
5. Quartz tubes' chemical stability at high temperatures is unmatched by any other
engineering material.
6. Quartz tubes have good Thermal Stability: Low thermal expansion coefficient, capable
of withstanding drastic temperature changes.
7. Quartz tubes have good Light Transmission: Excellent light transmission performance
across the entire spectrum, with visible light transmission rates
above 93%.
8. Quartz tubes have good Electrical Insulation Performance: Extremely high resistance,
making it an excellent electrical insulation material.

Q&A:
1. Q: What is a quartz tube used for?
A: Quartz tubes can be used for mercury lamps, high-pressure
mercury lamps, xenon lamps, ultraviolet lamps, iodine tungsten
lamps, halogen lamps, gas laser lamps, metal halide lamps, and
other electric light sources
2. Q: Are quartz tube heaters efficient?
A: Although they cost around the same price to buy, it's important
to bear in mind, that quartz heaters are more efficient than
ceramic heating elements.
3. Q: What is the difference between a glass tube and a quartz
tube?
A: Quartz glass tube is a special industrial technical glass made
of silica, which has a series of excellent physical and chemical
properties such as higher hardness and transparency than normal
glass tubes.
