Effect of dopants on high alumina ceramic materials

Abstract

Investigations were carried out on the effect of dopants on the sintering behaviour of high alumina ceramics. The dopants were Ti02, Sn02 and (Ti02+Sn02). The effects of different dopants, viz. 1, 3 and S wt% of Ti02, Sn02 and (Ti02 1+SnO,) on the sintering of alumina were studied at various temperatures (1300°, 1400°, 1450° and 1600T) and soaking times (10, 30, 50, 100 and 150 mins). The study revealed that 5 wt% of (TiOd+SnO,) gave the maximum densification at 1600°C and 150 mins soaking period. © 1986 Taylor & Francis Group, LLC.
