Температура спекани  должна быть достаточной дл  того, чтобы спечь поверхность порошковой заготовки, и выбираетс  в пределах 1200-1600С.The sintering temperature must be sufficient to bake the surface of the powder blank, and is selected from 1200 ° C to 1600 ° C.

Гор чее изостатическое прессование осуществл ют в печной камере, окруженной камерой давлени , при 800-1500°С и давлении 100-2000 бар, при этом давление прессующей среды действует непосредственно на поверхность заготовки. Предпочтительный размер зерен 1-8ц.Hot isostatic pressing is carried out in a furnace chamber surrounded by a pressure chamber at 800–1500 ° C and a pressure of 100–2000 bar, while the pressure of the pressing medium acts directly on the surface of the workpiece. The preferred grain size 1-8ts.

Способ применим также дл  изготовлени  электрических тепловых элементов, например из MoSi2 и стекла. Порощковые заготовки спекают при 900-1400°С, после чего их изостатически прессуют под действием прессующей среды при давлении 100-2000 бар и 800-ИОО С. Предпочтительный размер зерна порошка пор дка 1-75ц.The method is also applicable to the manufacture of electrical thermal elements, for example, MoSi2 and glass. Powder blanks are sintered at 900-1400 ° C, after which they are isostatically pressed under the action of a pressing medium at a pressure of 100-2000 bar and 800 PSI C. The preferred grain size of the powder is in the order of 1-75 c.

Предлагаемый способ может быть использован дл  керметов типа AlgOs-Ag, изготавливаемых прессованием порошка, имеющего размер зерен 1-50|.i, спеканием в вакууме при 900-1400°С и последующим гор чим изостатическим прессованием при давлении 100-2000 бар и 800-1400С.The proposed method can be used for AlgOs-Ag type cermets produced by pressing a powder having a grain size of 1-50 | .i, sintering in vacuum at 900-1400 ° C and subsequent hot isostatic pressing at a pressure of 100-2000 bar and 800- 1400С.
