摘要
The influence of additives on the sintering behavior of Cr2O3 was studied. The oxygen pressure and temperature at which the sintering rate becomes significant are dramatically altered by adding ∼ 1 wt% TiO2; the sintering temperature decreases, whereas the oxygen pressure for appreciable densification increases. At temperatures as low as 1280°C, densities of 92% of theoretical were obtained. Densification was examined as a function of temperature, oxygen pressure, and TiO2 concentration. Several other transition metal oxides were tested for their ability to enhance sintering; none was successful. Copyright © 1979, Wiley Blackwell. All rights reserved
