Sintering of mechanically activated ZnO- TiO2 powders

Abstract

Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetaiy ball mill and sintered under nonisothermal and isothermal condi- tions. Nonisothermal sintering is studied using dilatometry and SEM. The activation energy of sintering is determined using the method based on dijferent heating rates and Dorn"s method as well. The phase composition of the isothermally sintered samples is determined using x-ray powder diffraction.
