| Popis: | The effect of the sintering temperature on the density and electrical resistivity of Al2O3 based materials containing 30% TiB2 (specimen A) or 30% SiC (specimen B) is studied. As the temperature rises in the range 1873–2023 K the relative density of the materials increases from 0.68 to 0.76 (A) and from 0.70 to 0.88 (B) the electrical resistivity decreases from 2.6·104 to 2.9·102 Ω·cm (A) and from 7.4·104 to 6.3·102 Ω·cm (B). The results can be used in the development of corundum-based ceramic heaters. |
