The glass is transparent and has stable performance. Various types have different characteristics depending on the application, and the scope of application is very wide. When we choose glass, in addition to paying attention to the price, we should also have a certain understanding of its type and performance, and learn from the shortcomings to find a more suitable material。 For example, quartz glass is commonly used in the fields of optics and electronics, while glass is generally processed into various doors and windows and glass furniture, and ceramics are often used as tableware。 We will introduce the differences between these types to help you understand.
What is the difference between transparent quartz glass and general glass?
Both quartz glass and ordinary glass contain silica, but ordinary glass is made of a large amount of sodium silicate, and quartz glass contains a large amount of silica. Therefore, the composition is very different. .
Therefore, it can be understood that quartz glass is made of special glass made of silica, so its hardness and transparency are higher than that of ordinary glass. It has high temperature resistance, wear resistance and resistance to attack sometimes. Often these are ordinary glass. No。
What is the difference between ceramic and glass?
Ceramic is a polycrystalline metal oxide, glass is a polycrystalline silica, and ordinary glass may be doped with other metal oxides. Ordinary glass is silica, sodium silicate, calcium silicate. Mixture, special glass can be pure silica, or ordinary glass with lead, boron, antimony and other elements。 Quartz is pure silica。 Cement is a powdery hydraulic inorganic cementitious material, divided into six categories, namely silicon Salt cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement.
There are many semiconductor materials, which can be divided into elemental semiconductors and compound semiconductors according to their chemical composition。 Compound semiconductors include Group III and Group V compounds (gallium arsenide, gallium phosphide, etc。), Group II and Group VI compounds (cadmium sulfide)。 , zinc sulfide, etc。), oxides (oxides of manganese, chromium, iron, copper), and solid solutions composed of III-V compounds and II-VI compounds (gallium aluminum arsenide, gallium arsenide phosphorus, etc。)。 In addition to crystalline semiconductors, there are amorphous glass semiconductors, organic semiconductors, etc.
