Quartz glass, also known as fused silica, is a high-purity glass made from pure crystalline silica. It is an excellent material for a variety of applications due to its unique properties, including:
Chemical Properties
Inert to most chemicals, including acids and bases, which makes it an ideal material for use in chemical and pharmaceutical industries.
Resistant to chemical attack by molten metals and glasses, which makes it suitable for use in high-temperature applications such as furnace tubes.
Thermal Properties
High thermal shock resistance due to its low coefficient of thermal expansion, which makes it suitable for use in high-temperature applications where sudden temperature changes occur.
High thermal conductivity, which makes it an excellent material for use in heat exchangers and other thermal applications.
The high melting point of approximately 1713°C, which makes it suitable for use in high-temperature applications.
Optical Properties
High optical clarity and transparency in the UV, visible, and IR regions of the electromagnetic spectrum, which makes it ideal for use in optics and photonics applications.
Low birefringence, which makes it suitable for use in polarization-sensitive applications such as waveplates and polarizers.
Mechanical Properties
High mechanical strength and hardness, which makes it resistant to scratching and damage during handling and use.
Low coefficient of thermal expansion, which reduces the risk of thermal stress and fracture.
Low coefficient of friction, which makes it suitable for use in bearings and other sliding components.
Electrical Properties
Excellent electrical insulation properties, which makes it ideal for use in high-voltage applications such as insulators and electrical feedthroughs.
High dielectric strength, which makes it suitable for use in high-power electronics applications.
Physical Properties
High density of approximately 2.2 g/cm³, which makes it heavier than most other glasses.
High refractive index of approximately 1.46, which makes it an excellent material for use in optics and photonics applications.
Low thermal expansion coefficient of approximately 0.5 x 10^-6 /°C, which makes it suitable for use in high-temperature applications.
