High borosilicate glass

  High borosilicate glass (also known as hard glass) is characterized by the use of glass to conduct electricity at high temperatures. The glass is melted by heating inside the glass and processed by advanced production processes. The coefficient of thermal expansion is (3.3 ± 0.1). ) × 10-6 / K, also known as "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source. , craft jewelry and other industries. Its good performance has been widely recognized by all walks of life around the world, especially in the field of solar energy, and developed countries such as Germany and the United States have carried out more extensive promotion.

   

  Production process

  Made of borosilicate glass, water glass sand, soda water and ground lime added to the glaze made of boron traditional glass. Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new technologies are needed to make industrial production. Borrowing from the welding trade, combined with the need for new natural gas to burn oxygen.

  Characteristic

  Borosilicate glass has a very low coefficient of thermal expansion, about one-third that of ordinary glass. This will reduce the effects of temperature gradient stress and thus have stronger fracture resistance. Due to its very small shape deviation, this makes it an indispensable material in telescopes and mirrors. It can also be used to treat high-level nuclear waste. The borosilicate glass begins to soften at about 821 ° C ( 1510 ° F), at which temperature the 7740 viscosity borosilicate is 107.6 farmar.
