Quartz glass tube is made of silica  special industrial 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 is about 1730°C. It can be used for a long time at 1100°C, and the maximum use temperature can reach 1450°C in a short time.
2. Except for 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 types: transparent quartz tubes (outer diameter 1.5mm-300mm), UV-filtered quartz tubes, colored quartz tubes, etc.
Quartzite can be used to manufacture glass, refractory materials, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, casting. Quartzite is used in the building to have strong resistance to acid media erosion, and is used to make acid-resistant concrete and acid-resistant mortar .
As the core raw material of silicon raw material, silicon dioxide plays an irreplaceable and important role in the production and supply of silicon raw material. Its unique physical, chemical and optical characteristics make it play an increasingly important role in many high-tech products, such as the core technology products of the IT industry-computer chips, optical fibers, and resonators in the electronics industry New electric light sources, high-insulation sealing materials, aerospace equipment, military technology products, special optical glass, chemical analysis instruments, etc. are inseparable from these basic raw materials.
