High Quality Wholesale Price Quartz Crucible for Quartz Tube Furnace

 

Main Features: 

High-purity quartz products are special industrial technical glass made of high-purity silica, which is a very good basic material. Quartz crucible have a series of excellent physical and chemical properties such as:
1. High temperature resistance. The softening point temperature of quartz glass is about 1730°C, which can be used for a long time at 1150°C, and the maximum temperature can reach 1450°C in a short time.
2. Corrosion resistance. Except for hydrofluoric acid, the high-purity quartz crucible hardly reacts with other acids. At high temperatures, it is resistant to corrosion by sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon and sulfur. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperatures, which is unmatched by any other engineering material.
3. Good thermal stability. The high-purity quartz crucible has a very small thermal expansion coefficient and can withstand drastic temperature changes. The high-purity quartz crucible is heated to about 1100°C, and it will not burst when placed in room temperature water.
4. Good light transmission performance. The high-purity quartz crucible has good light transmittance 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 light transmittance can reach above 80%.
5. Good electrical insulation performance. The resistance value of high-purity quartz crucible is equivalent to 10,000 times that of ordinary quartz glass. It is a good electrical insulating material and has good electrical properties even at high temperatures.
