Advantages of quartz glass include:
High heat resistance: The softening point temperature of quartz glass is about 1730℃, it can be used at 1100℃ for a long time, and the temperature can reach 1450℃ for a short time.
High corrosion resistance: Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids. Its acid corrosion resistance is 30 times better than that of acid-resistant ceramics and 150 times better than stainless steel.
Good thermal stability: Quartz glass has a very small thermal expansion coefficient and can withstand drastic temperature changes. Even if quartz glass is heated to about 1100°C, it will not explode when placed in normal temperature water.
High light transmittance: Quartz glass has high spectral transmittance and will not be darkened due to radiation damage. It is an ideal material for spacecraft, wind tunnel windows and spectrophotometer optical systems.
Electrical insulation: Quartz glass has excellent electrical insulation properties and can be used to manufacture electric vacuum devices and high-voltage insulating materials.
Good chemical stability: Quartz glass has a high degree of chemical stability and can resist the erosion of various chemical substances. It is widely used in chemical laboratories and industrial production fields.
