What are the advantages and characteristics of quartz glass

For outsiders, there may be very few types of glass, as most glass appears "the same" in appearance. But for glass practitioners, there are so many types of glass that I am not even sure if I can list them completely.

The reason why it is called quartz glass is because it is made by melting various pure natural quartz (such as common crystals, quartz sand, etc.), and the word "pure" is the key. Next, let's talk about the many characteristics of quartz glass.

1. High purity

The quartz mentioned earlier is composed of silicon dioxide (SiO2), which is also the main component of many types of glass.

2. High temperature resistance

Of course, the reason why quartz glass can be used in numerous scientific research scenarios is based on its heat resistance. Generally speaking, the operating temperature of quartz glass is 1100 ℃~1200 ℃, and even for short-term use, it can withstand high temperatures of 1400 ℃.  

3. Good thermal shock resistance

This is because quartz glass has a very small coefficient of linear expansion, which is 1/10~1/20 of ordinary glass, and has good thermal shock resistance.  

4. Excellent optical performance

The optical performance mentioned here is mainly reflected in light transmittance, ultraviolet and infrared transmittance.  

5. Strong acid resistance

Except for hydrofluoric acid and hot phosphoric acid above 300 degrees, quartz glass has good acid resistance. Quartz glass has good tolerance to sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, etc.
