Semi-finished products for the production of electronic equipment.

Materials for electronic equipment are divided into three groups: glasses, phosphors and refractory metals.

About 50 brands of glasses are used for the production of electronics.

Some brands are displayed on the screen.

Molybdenum and tungsten glasses are used for the manufacture of screens and cones of kinescopes, flasks and cylinders operating under thermal loads.

The manufacture of glass elements begins with the manufacture of the charge.

The process is demonstrated in a laboratory, the composition of the charge components is determined.

In production, the components of the charge are thoroughly mixed and fed into the melting furnace.

Workshop for the production of special glass.

The widespread use of glass in electro-vacuum production is explained by a number of its valuable properties, the main of which is the comparative ease of shaping.

Forming cones and screens of kinescopes.

Blowing, pulling glass blanks.

Thermoplastic glass processing method.

Heat treatment of glass by annealing in special furnaces.

Conveyor line for the production of kinescopes.

Grinding and polishing of glass products.

The advantage of glass as a material is that the individual elements can be joined together using various adhesives.

The cone and the screen are glued together with glass cement.

The quality of the materials and the strength of the joints are checked using spectral analysis and vibration treatment.

For the manufacture of television tubes, lighting fixtures and a screen, a three-component mixture is applied to the inner surface, which is a phosphor suspension.

To improve the adhesion of the phosphor to the glass, a substrate of an aqueous solution of polyvinyl alcohol is applied.

The line of application of phosphor mixture.

A cartoon explaining this technological process.

To create the color gamut of the kinescope, three phosphor compositions are used.

In order to align the surface of the phosphor, an organic film is applied to the product.

After drying, the product is checked.

The control process.

Cartoon explaining the technology of improving the quality of the phosphor layer by vacuum spraying aluminum coating.

After applying aluminum, the product is fired, during which the organic film burns out.

After that, the product goes to the next quality control.

Samples of products for the electronic industry made of refractory metals.

Devices that carry out electrophysical processes, such as electronic emission, thermal emission and heating, are made of these metals.

The production of refractory metals is based on powder metallurgy technology.

A mixture of various refractory components prepared in a certain proportion is poured into trays and loaded into an annealing furnace.

One example of the composition of powders: tungstic acid, ammonia solution and some other alloying additives in small doses.

Liquid ammonia is removed in the furnace, resulting in tungsten anhydrite.

The resulting tungsten anhydrite is moistened with an alcoholic solution of glycerin, thoroughly mixed, placed in molds and pressed.

The shape of the resulting product is a stack.

The stacks are placed in a vertical electric furnace and sintered for 10-15 minutes.

Cartoon explaining the technological process of sintering refractory material.

Forging of the resulting stacks on a rotary forging machine.

Drawing and broaching through spinners, including through diamond spinners.

A cartoon showing the making of a diamond die.

Quality control of wire obtained from refractory materials.

The thinnest wires are obtained by electrochemical etching.

To give the wire protective and contact properties, it is gilded.
