Soda lime glass is usually called silicate glass, its main component is silicon dioxide (SiO2), and also contains a certain amount of sodium oxide (Na2O) and calcium oxide (CaO), and some other Auxiliary ingredients. Because it contains sodium oxide and calcium oxide, its thermal expansion coefficient is small, so it has good thermal shock resistance; at the same time, soda lime glass has very good light transmission and chemical stability, so it is used in the production of chemical instruments, optical Instruments, medical devices and other aspects have a wide range of applications.
The main components of high borosilicate glass are silicon oxide (SiO2) and boron oxide (B2O3), and also contain some other auxiliary components. Compared with soda-lime glass, high borosilicate glass has a smaller thermal expansion coefficient, so it has better heat resistance and thermal shock resistance; in addition, high borosilicate glass has better mechanical properties and chemical stability, and is more transparent and Radiation resistant. Therefore, it is widely used in nuclear industry, optoelectronic technology, semiconductor industry and other fields.
Although both soda-lime glass and borosilicate glass are inorganic amorphous materials, their difference lies in their chemical composition and properties. Soda lime glass is suitable for occasions requiring chemical stability and light transmission, while high borosilicate glass is more suitable for occasions requiring high heat resistance and radiation resistance.
