Customized Quartz Glass Plates with Step Slot

Customized Quartz Glass

Customized quartz glass plates / sheets are products within the scope of CNC machining. The precision of glass products processed by CNC is relatively high. If detailed drawings can be provided, processing will be easier. Slotting the edge of the quartz disc to achieve a stepped effect. After the finished product, there is usually a slight cracking phenomenon. This kind of breakage can also be avoided, but it will result in more defective products. This will directly lead to a higher increase in costs.

The main characteristics of quartz glass

1. Heat resistance

The softening point of quartz glass is 1730 ℃. It can be used for a long time below 1100 ℃, and the temperature for short time use is up to 1450 ℃.

2. Light transmission

Quartz glass has good light transmittance in the entire optical spectrum from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.

3. Electrical insulation

The electrical resistance of quartz glass is equivalent to 10,000 times that of ordinary glass.

4. Chemical stability

Quartz glass almost don’t react chemically with other acid-base substances except hydrofluoric acid.

5. Thermal stability

Quartz glass has low expansion coefficient, and it can withstand drastic temperature changes.

6. Hardness characteristics

With the hardness of Mohs level 7, the mechanical properties of quartz glass are better than hard glass and ceramics, and the strength of quartz glass improves with the increase of temperature, reaching its maximum when approaching the annealing temperature.
