Introduction to the physical properties of quartz wafers
Quartz sheet is a special industrial technical glass made of silica, which is a very good basic material. Quartz plates 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, and 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. Corrosion resistance. Except for hydrofluoric acid, quartz glass hardly reacts 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 impossible for any other engineering material. Comparable.
3. Good thermal stability. The thermal expansion coefficient of the adaptable 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 plates have excellent light transmittance in the entire spectrum from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectrum, the maximum transmittance can reach above 80.
