Nanocrystalline TiO 2 ultra5ne powders with di4erent grain sizes have been prepared by the sol+gel method. The grain sizes and the crystalline phases have been determined. Heat capacities in the temperature range of 78+370 K have also been measured, and the polynomial equations expressing the change
The effect of TiO 2 addition (0-4.0 wt%) on the sintering behavior and mechanical properties of an ultrafine (150 nm) alumina-5 wt% zirconia powder has been investigated. TiO 2 is a beneficial additive, resulting in lower sintering temperature and higher sintered density. The grain growth is shown t
