Materials in the system AE(2)O(3) (with additions of ZrO2, SiO2, CeO2,
Si3N4. AlN)-TiB2 containing titanium boride concentrations up to 70 w
t. % were prepared by sintering in carbon monoxide (T = 1873 K, t = 3
h). The relative density of these materials did not exceed 69% of theo
retical, with a minimum al approximately 38% TiB2 an the density la. c
omposition curve. The specific electrical resistance of the materials
decreased from 3.4.10(9) to 82 Omega.cm with increasing titanium borid
e concentration. An abrupt decrease in electrical resistance occurred
in the range 20-30% titanium boride.
