What are the advantages of JGS1 quartz glass?

In our daily lives, we often come into contact with various types of glass materials. In addition to traditional flat glass, there are also special-performance glass materials such as ultra-white glass and high-borosilicate glass, as well as common materials such as hollow glass and laminated glass. Let's take a look at the advantages of JGS1 quartz glass and the difference in its composition from crystal.

　　Why is JGS1 quartz glass commonly used in instruments?

　　High temperature resistance. The softening point temperature of JGS1 quartz glass is approximately 1730℃, and it can be used continuously at 1100℃ and for short periods at 1450℃.

　　Corrosion resistance. Except for hydrofluoric acid, JGS1 quartz glass almost does not react with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. In particular, its chemical stability at high temperatures is unmatched by any other engineering material.

　　Good thermal stability. JGS1 quartz glass has a very low thermal expansion coefficient and can withstand drastic temperature changes. If JGS1 quartz glass is heated to around 1100℃, it will not burst even if placed in room temperature water.

　　Good light transmittance. JGS1 quartz glass has good light transmission performance in the entire spectral band from ultraviolet to infrared. The visible light transmittance is over 95%, and especially in the ultraviolet spectral region, the transmittance can reach over 80%.

　　Good electrical insulation performance. The electrical resistance of JGS1 quartz glass is 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures. Due to its excellent physicochemical properties, JGS1 quartz glass is widely used in the fields of electro-optic sources, semiconductors, optical communication, military industry, metallurgy, building materials, chemicals, machinery, electricity, and environmental protection.

　　Difference in Composition between JGS1 Quartz Glass and Crystal

　　The main component of JGS1 quartz glass and crystal is silicon dioxide, but they are not exactly the same.

　　JGS1 quartz glass is made by melting various pure natural JGS1 quartz glasses (such as crystal and quartz sand). It has a very small linear expansion coefficient, 1/10 to 1/20 that of ordinary glass, and has good resistance to thermal shock. JGS1 quartz glass is an amorphous material with a single component of silicon dioxide. Its microstructure consists of a simple network of structural units with a tetragonal structure of silicon dioxide. Due to the large silicon-oxygen chemical bond energy and tight structure, JGS1 quartz glass has unique properties.

Crystal is a rare mineral, a gemstone, and a quartz crystal. In mineralogy, it belongs to the quartz family. The main chemical component is silicon dioxide. When the crystal of silicon dioxide is complete, it is a crystal; incomplete crystals are when: after dehydration of silica gel, it becomes agate; after the hydration of silica gel solidifies, it becomes opal; when the particle size of silicon dioxide is less than a few micrometers, it is composed of chalcedony, flint, and secondary quartzite.

The above are some key points about JGS1 quartz glass, hopefully this will help everyone.
