Electro-vacuum glasses/glasses for the electronics industry
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.

Shvabe Description
The main official document for electrovacuum glass is the industry standard of glass OST 11 027.010-75.
Brands of electric vacuum glasses are marked with the letter C-the initial letter of the word "Glass".
The number in the glass label indicates the value of the thermal expansion coefficient.
The purpose (scope):
Electrovacuum glass is used for manufacturing electron-optical converters (EOP), semiconductor
photovoltaic radiation receivers (photodetectors), electrovacuum devices of generator lamps,
transmitting tubes, and photomultipliers. Electrovacuum glass is used for shells and parts of the internal
device of electrovacuum devices, electric lighting lamps (incandescent lamps), radio tubes, electron-
beam tubes and kinescopes, solar cells, etc.
Produced at JSC " lytkarinsky optical glass plant"
