SEMICONDUCTOR CERAMIC MATERIAL Russian patent published in 2006 - IPC H01C7/04 

FIELD: electric engineering, in particular, engineering and manufacture of thermo-resistors.

SUBSTANCE: semiconductor ceramic material is made on basis of composition Y(Ba_1-XBe_X)₂Cu₃O₇, where 1 ≥ x ≥ 0,7, produced by mixing source powders Y₂O, BaCO₃, BeO, CuO in water-less spirits, their pressing under pressure of 10 atmospheres and baking at temperature 920-1100°C, during which Be is partially replaced with Ba, contained in skull of ceramics on basis of Y(Ba_1-XBe_X)₂Cu₃O₇, where 0,001 < x < 0,4 with production of several solid solutions.

EFFECT: creation of semiconductor material, resistant to thermal, mechanical and electrical loads, with broad conductivity spectrum ranging from 1·10^-2 to 2,5·10² Ohm·meter.
