Honesty ROHS certification clear quartz tube
Character:
Clear quartz tube is good acid-resisting material,except hydrofluoric acid and over 300 degrees hot phosphoric acid,under the high temperature,clear quartz tube’s erosion ability of sulfuric acid,nitric acid,hydrochloric acid and aqua regia,neutral salt,carbon and sulfur,such as clear quartz tube chemical stability is equivalent to 30 time of acid-resistant ceramics,equivalent to 150 time of the nickel chromium alloy and ceramic.
Clear quartz tube’s high temperature resistant,heat resistant, thermal expansion coefficient is very small.
Clear quartz tube has excellent electrical properties.At room temperature,its resistance is equal to 10 time the ordinary glass,the dielectric loss is very small for all frequency and having big insulation compression strength.
Clear quartz tube also has the cosmic radiation resistance,and not through the nature of the nuclear fission products.
Clear quartz tube is also used in: chemical technology, metallurgical technology,electrical technology, scientific research, etc
