Vitreous solder glasses

One must distinguish between vitreous solder glasses and devitrify ing solder glasses, according to their behavior during the soldering process. 

The important uses of lithium fluoride are as flux in glasses, vitreous enamels and glazes in soldering and welding aluminum and its prisms in infrared spectrophotometers. The compound also is used for storing solar energy.

Dielectric overglaze materials are vitreous glasses designed to fire at a relatively low temperature, usually around 550° C. They are designed to provide mechanical protection to the circuit, to prevent contaminants and water from spanning the area between conductors, to create solder dams, and to improve the stability of thick-film resistors after trimming.
