Inventory of the 6 core advantages of quartz glass sheets

 To the uninitiated, there may be few types of glass, as most glass is "the same" in appearance. But for glass practitioners, there are so many types of glass that I am not sure if I can list them all.

In this article, let's talk about a glass that is widely used in the field of technology research and development: quartz glass. Let's talk about the concept of quartz glass first.

The optical properties of the quartz glass plate have its own uniqueness. It can not only transmit far ultraviolet rays, which is the best of all ultraviolet transmissive materials, but also transmit visible light and near-infrared spectrum. Because quartz glass has the characteristics of high temperature resistance, extremely small thermal expansion coefficient and good chemical stability, it is an indispensable optical material to achieve high and stable optical performance in various harsh occasions.

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

1. High purity

The quartz mentioned above is silicon dioxide (SiO2) in composition, and the main component of many kinds of glass is also silicon dioxide. The content of silica in quartz glass is much higher than that of ordinary glass, usually as high as 99.999%. You say, is it very "pure"?

2. High temperature resistance

Of course, the reason why quartz glass can be used in many scientific research scenarios is based on its high heat resistance. Generally speaking, the use temperature of quartz glass is 1100 ° C ~ 1200 ° C, and even if it is used for a short time, it can withstand a high temperature of 1400 ° C.

3. Good thermal shock resistance

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

4. Excellent optical performance

The optical properties mentioned here are mainly reflected in light transmittance, ultraviolet and infrared transmittance.

5. Strong acid resistance

Except for hydrofluoric acid and hot phosphoric acid above 300 degrees, the acid resistance of quartz glass is relatively good. Including sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, etc., quartz glass has good tolerance.

6. Excellent electrical performance

Quartz glass not only has excellent optical properties, but also performs very well in electrical properties. At room temperature, the resistance of quartz glass is 10 times that of ordinary glass, the dielectric loss to all frequencies is very small, and the dielectric strength is high. Quartz glass is mainly used in electric light sources, semiconductors, new optical technologies, etc.

Formally based on the temperature resistance, acid resistance, low expansion, high transmittance and excellent electrical properties of quartz glass, it has become an important material in modern science and technology. Quartz glass is used in high-tech fields such as semiconductor industry, optical communication, and electric light source.
