摘要：

A comparative study of sintering of different nanocrystalline TiO2 powder materials has been made. Two types of powders (produced by gas condensation and wire explosion methods) and two techniques of compacting were used for the fabrication of the green samples. Microwave and conventional sintering have been compared too. Grains grow dramatically with increasing of the density of samples. No significant dependence of the grain size on the methods of fabrication of powders, technique of compacting or method of processing has been found. Despite the larger amount of the anatase, the microhardness of microwave sintered samples is about 10% higher than that of the conventionally sintered samples. (C) 1999 Acta Metallurgica Inc.
