Properties of Quartz Glass

Quartz glass has low coefficient of thermal expansion, high heat resistance, good chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, high light transmittance in UV-VIS-NIR spectrum performance, and has higher mechanical properties than ordinary glass.

Quartz glass is considered acid material, in addition to hydrofluoric acid and hot phosphoric acid, it is inert to any other acid, which determines is is a good acid-resistant material. At room temperature, the corrosion degree of alkali and salt to quartz glass is also small, so it is also possible to use quartz glass in these reagents.

Quartz glass has a high dielectric strength and low conductivity, even at high temperature, high pressure and high frequency, it can still maintain a high dielectric strength and electrical resistance, and there is almost no dielectric loss in the applied frequency band, because quartz glass is an excellent high temperature dielectric insulation material

The optical properties of quartz glass are unique, which can pass through the 185-3500nm, and it is the priority of all UV-transmitting materials. Because the outstanding physical properties of quartz glass, and the bubble, the streak, the uniformity, the birefringence can be comparable to the general optical glass, so it is an essential optical material for working in a variety of harsh occasions with high stability optical system.


Optical Glass Use Instructions

1. Quartz glass products are valuable materials and must be handled with great care when used

2. All kinds of glass have the highest use temperature, which should not be exceeded when used, otherwise it will crystallize, or soften and deform.

3. Quartz glass that needs to be used at high temperatures must be wiped clean before use. Can be soaked with 10% hydrofluoric acid or lotion. Then wash with high-purity water or alcohol. Wear fine thread gloves during operation. Do not touch the quartz glass directly with your hands

4. Allow continuous use of glass products at high temperatures, which is good for extending the life of glass and improving high-temperature resistance. On the contrary, the intermittent use of quartz glass products at high temperatures has a limited number of uses.

5. Although the use of glass material has strong thermal stability, it can withstand severe temperature differences, but in actual use, due to the residual strain and the shape of the product, the thermal stability has a certain difference. Be careful when using.

6. Quartz glass coefficient acidic materials, high-temperature use strictly avoid contact with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.), otherwise it will greatly reduce its crystallization resistance.
