Abstract:
A sorption apparatus for gas purification consists of a vertical flow column with gas tight walls, inlet and outlet filters, and a disintegrator producing reactive powder in the medium of the gas to be purified at ambient temperature, i.e. without forced heating or cooling. A process of sorption purification of gas flow using the sorption apparatus, where the reactive powder is produced as needed by mechanical milling of a monolithic ingot structure in the medium of the gas to be purified and a reactive sorption material. The composition of the sorption material corresponds to an eutectic on the basis of a reactive metal Me or an intermetallic compound MenM with a relatively low melting point, where M is the second metal and n 2:1, wherein the sorption material is obtained according to the above process.
Abstract:
Apparatus and method for the production of shaped reactive alloys are disclosed. The shaped reactive alloys are obtained by controlled droplet casting in inert atmosphere, wherein the droplets are produced by using mechanical force on a metallic ampoule containing the molten alloy. The manufacture of gas sorbent and elements for vacuum systems according to the above method are also described.
Abstract:
A method for preparation of a getter material on the basis of intermetallic compounds of barium is described. The method comprises preparing a melt of a ternary mixture containing barium, metal and sodium; directionally solidifying the melt to produce a textured ingot; granulating the textured ingot, thereby obtaining granules having open-ended voids extending therethrough; and evaporating the sodium from the granules by applying a thermovacuum treatment to the granules. The textured ingot comprises a getter body made of intermetallic compounds of barium; and open-ended voids within the getter body.

Abstract:
Plate-shaped composite getter materials for the sorption of gases containing two interpenetrating constituents, a reinforcing component of skeletal framework and a reactive matrix, which form a coherent monolithic structure, a method for producing such composites, and their application in vacuum technology or gas purification are described. A synthetic getter composite of the classical type in the form of a thin monolithic plate with two constituents, a reinforcing framework embedded in a reactive matrix, has been developed. Metallic gauze made of high-melting transitional metals or their alloys is used as a reinforcing constituent and a reactive metal or alloy with a high concentration of this metal is used as the reactive matrix.
