Sintering of chromium oxide

Green chromium oxide compacts incorporating TiO, as dopant were sintered at 1400., 1450. and 1500.C respectively in conditions simulating controlled atmosphere firing having a very low p 0 2. Studies on the microstructure, density, porosity and hardness revealed that 1.0 wt of T i02 caused densification to the extent of 95.59 per cent of theoretical when fired at 1500.C with 0.5 hr soaking. A higher percentage of Tio2, however, resulted in inferior properties. © 1985 Taylor & Francis Group, LLC
