Non-silicate optical colorless inorganic glass. In its composition, the special crown is a pure fluoro- phosphate glass. The main components are fluorides of elements I, II, and III of the periodic table and metaphosphates.

Inorganic silicate glasses contain compounds of fluorine or sodium fluoride that provide glass silencing. In the process of technological guidance of transparent glass, crystals with a refractive index that differs from the refractive index of glass are isolated and make the glass opaque, which in appearance looks like "solid milk". Unusual crystallization of glass is called zaruhaniem and is characterized by the size (about 100nm, 200nm and 1mkm) of crystals and the number of crystals (about 100,000 PCs.) in 1mm3.

Electro-vacuum glasses combine a large group of glasses used in radio-electronic technology. The compositions of electrovacuum inorganic glasses are very diverse. Basically, these are borosilicate glasses, in which the main addition to silicon dioxide is boron oxide B203 and other elements of the periodic system in relatively small quantities, which provide the necessary coefficient of thermal expansion and viscosity of the glasses for vacuum-strong connection of the metal with such glasses by welding or soldering.

Special glasses

Laser glasses on both silicate and phosphate bases, activated with neodymium with different activator concentrations, have been developed.
