| Applications As the basic raw material of boron compounds, it is also used in glass, enamel, non-ferrous metal welding, fertilizer, atomic energy industry and electronic tubes, etc. Mainly used in capacitor manufacturing, disinfection and antiseptic drugs; used to prepare processing fluid for exposed photosensitive materials. In special optical glass, glass fiber, non-ferrous metal solder, jewelry binder, printing and dyeing, washing (silk and wool fabric, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and pharmaceuticals Disinfectants are also widely used | ||
| Storage Store in a cool, ventilated and dry warehouse, borax is easy to melt, so wrap it with kraft paper and seal it, and it should not be mixed with wet items or other colored materials |
