The composition is different, the composition of high borosilicate glass is sodium oxide and boron oxide. Silicon dioxide has a relatively high content of borosilicate in glass: 12.5-13.5%, silicon: 78-80%, and silica glass is composed of silica: the content is 99.99.
The temperature resistance is different: the high borosilicate temperature is 520 degrees at the strain temperature and 820 degrees at the softening temperature. The temperature of quartz glass is 1100 degrees and the melting point is about 1700 degrees.Quartz glass is not only resistant to high temperatures, but also resistant to acids and corrosion. Good electrical insulationOpal Opaque Quartz Glass Suppliers, etc.Borosilicate glass manufacturing, adding water glass sand, soda water and ground lime with the glaze of boron traditional glass manufacturing.
Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new technologies are needed to enable industrial production. Borrowing from the welding trade, combined with the need for new natural gas combustion oxygen. The fire resistance and physical strength of borosilicate glass make it an ideal choice in the laboratory. It is used to manufacture high-durability glass such as beakers and test tubes in laboratory equipment. In addition, the minimal exposure to borosilicate glass bending allows the volume of the borosilicate heat-resistant container to provide an accurate measurement over a period of time.
In the middle of the 20th century, borosilicate glass tube coolant was used (usually distilled water) to pass high-power vacuum tube-based electronic equipment, such as commercial broadcast transmitters.
Glass cookware is another common usage. A borosilicate glass pie plate is almost an American standard plate. The borosilicate glass measuring cup, with a mark on it to indicate graduation, is also widely used in American kitchens.
Quartz glass is a special glass containing only a single component of silicon dioxide. Due to differences in types, processes, and raw materials, foreign countries are often called silicate glass, quartz glass, fused quartz, fused quartz, synthetic fused quartz, and transparent,
translucent, and opaque quartz without clear concepts. my country is collectively referred to as quartz glass, which is mostly classified according to process method, use and appearance, such as fused transparent quartz glass, continuous fused quartz glass, gas-melted transparent quartz glass, synthetic quartz glass, opaque quartz glass, optical quartz glass, quartz glass for semiconductors , Quartz glass for electric light sources, etc. People are accustomed to naming this material with a simple word like "quartz", which is absolutely inappropriate, because"quartz" is a general term for the crystalline state of silica, and it has physical and chemical properties with glassy silica.
