Designed for welding ferrite and ceramic knots. They have good adhesion to ceramics and ferrites

Optical colorless inorganic glasses have a high optical uniformity, the deviation from which is estimated by tenths of a percent. A wide range of optical glasses is determined by the variety of their chemical composition. In this case, the composition of each type of glass is characterized by the content of some elements of the periodic system, changing in relatively small quantities. Optical glasses are divided into two large groups – crowns and flints, and the glasses of each group are divided into types.

Optical colored inorganic glasses are glasses colored in mass. Optical colored inorganic glasses provide isolation or absorption of part of the spectrum from ultraviolet to infrared. The selection of a part of the spectrum in glasses is formed by color centers (different types of electronic transitions).

Infrared glass (dark infrared).

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.

Non-silicate optical colorless inorganic glass.

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.
