4. Lower price
1. Purity:
SiO2 content is more than 99.9%, transparent quartz tube can reaches above 99.95%
2. Temperature:
Softening point temperature is about 1730 degrees Celsius, 1100 degrees Celsius in a long time used, short-time maximum use temperature is up to 1450 degrees Celsius;
3. Anti-corrosion:
Quartz glass is acidic materials, except hydrofluoric acid and 300 degrees Celsius thermal phosphoric acid, on any other acids were shown to be inert, is the best anti acid materials. At room temperature, alkali and salt on quartz glass corrosion degree is minimal.
4. Transmittance good performance:
Compare to ordinary silicate glass, transparent quartz glass in the whole wavelength head excellent permeability. In the infrared spectrum through than ordinary glass; In the visible region, quartz glass transmittance is relatively high, above 85%-90%. In the UV spectral region especially in the ultraviolet region, the spectral transmission is much better than other glass, about 80%.
5. Good electrical insulation properties:
Quartz glass with high dielectric strength and very low electrical conductivity, even in high temperature, high pressure and high frequency, it can still maintain high dielectric strength and resistance, in the application of the band almost no dielectric loss, therefore the quartz glass is an excellent high temperature dielectric insulating material
6. Thermal stability:
The thermal expansion coefficient of quartz galss is extremely small, it can be able to adapt drastic temperature changes;
Our company uses advanced technology and unique formulations produced high-quality quartz tube with square mouth.
Infrared tracking measurements, infrared photography, communications, spectrograph, spectrophotometer prism, lens, large astronomical telescope reflector windows, high-temperature windows, reactors, radioactive devices; Rocket and missile nose cones, nozzles and radome, satellite radio insulation parts, radiation, thermal scales, vacuum adsorption unit, precision casting and so on. Chemical industry: Do high-temperature acid-gas combustion, cooling and ventilation equipment, acidic solution, evaporation, cooling absorption material received, storage devices, distilled water, hydrochloric acid, nitric acid, sulfuric acid, etc. Preparation and other physical chemistry experiment supplies.
In the high-temperature areas: Optical glass crucible can do phosphor firing polite, electric furnace core tube, gas burning radiator, thermocouple protection tubes. In the electrical field: Do high-pressure high-frequency insulation tubes, cited wave tubes.
High purity: purity is an important index of quartz glass, ordinary quartz glass content of more than 99.99% SiO2, high purity synthetic vitreous SiO2 content of more than 99.999%.
Thermal properties: heat resistance than any glass of quartz glass, a transparent quartz glass can withstand the high temperature 1100 ºC ~ 1150 ºC working conditions of long-term use.
thermal stability: quartz glass linear expansion coefficient is extremely small, it has high thermal stability. Has to withstand severe temperature changes without the ability to burst.
mechanical properties: hardness transparent quartz glass is 6 to 7 Mohs, pressure 14,000 kg / cm 2, bending 700 kg / cm 2, the specific gravity of 2.903, the mechanical properties significantly better than Hard glass and ceramics.
chemical properties: quartz glass material is good acid, the chemical stability of the ceramic is equivalent to 30 times the acid, in addition to more than 300 ºC hydrofluoric acid and phosphoric acid, is not corrupted by other acids.
optical properties: quartz glass having good spectral characteristics, it can be transparent to ultraviolet and infrared rays, high-purity synthetic quartz glass can penetrate deep UV and anti-r-rays.
