The physical and chemical properties of quartz tube bai   Quartz glass tube is made of du silica [1] special industrial zhi technology glass, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as: 1. The softening point temperature of high temperature resistant quartz glass white fused quartz tubeis about 1730°C, and it can be used for a long time at 1100°C. The maximum use temperature can reach 1450°C in a short time. In addition to hydrofluoric acid, quartz glass hardly reacts chemically with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially, its chemical stability at high temperatures is the same as any other engineering material. incomparable. 3. Good thermal stability


The thermal expansion coefficient of quartz glass is extremely small, and it can withstand severe temperature changes. When the quartz glass is heated to about 1100°C, it will not burst when placed in water at room temperature. 4. Good light transmission performance    Quartz glass has good light transmission performance in the entire spectrum band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach above 80. 5. Good electrical insulation performance   

The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulation material and has good electrical properties even at high temperatures.   Quartz glass has the above-mentioned excellent physical and chemical properties, so it is widely used in electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, environmental protection and other fields. (The information is for reference only!) Types of quartz tubes   Quartz tubes can be roughly divided into the following categories: transparent quartz tubes (outer diameter 1.5mm-300mm), UV-filtered quartz tubes, colored quartz tubes, etc.
