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.

Silicate inorganic glass.

Special glasses

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

We manufacture steel welded H-beams of uniform cross-section and variable cross-section in accordance with ТУ 5260-005-62361323-2013 on effective up-to-date equipment for using them as details of framing supporting constructions: columns, roof and floor beams of buildings and facilities of different purpose.
