Soldering glass

Soldering glass, also known as glass solder, is a specialized material used to create robust and hermetic seals between glass and metal components, making it essential for high-precision applications requiring airtight and durable connections. Its properties include excellent hermetic sealing, high thermal stability, chemical resistance, low thermal expansion, and good electrical insulation. These characteristics make soldering glass ideal for various applications such as sealing electronic components in electronics and microelectronics, encapsulating optoelectronic devices, protecting sensitive components in aerospace and defense, ensuring sterility and durability in medical devices, manufacturing telecommunications devices, and constructing vacuum equipment. Its versatility and unique properties make it invaluable across these industries.
