Product Overview
Low melting point glass powder is an advanced sealing material introduced by ANYWHERE POWDER researchers, which has a low melting temperature and sealing temperature, good heat resistance and chemical stability, high mechanical strength, and is widely used in vacuum and microelectronics technology, laser and infrared technology, high energy physics, energy, aerospace, automotive and many other fields. This product can be used in the mutual sealing between glass, ceramics, metals and semiconductors. It enables sealing between glass, ceramics, metals and semiconductors. As a new material, low melting point glass powder has been used in some new materials, but the application prospects are far beyond the current encounter, and still need to be explored and expanded by researchers.
- Low melting point glass powder has different names in different application fields.
- In the field of flame-retardant rubber and plastic, known as: Ceramic powder.
- In the field of sintered materials for precision devices, known as: Inorganic solder/Soldering-flux.
- In the field of industrial catalysts, high-temperature fluxes, known as: Inorganic solvent.
- In the field of fireplace high-temperature ink and low-temperature ceramic color glaze, known as: Inorganic ink.
- In the field of bonding materials for special optical instruments and metal precision instruments, known as: Inorganic sealant.
