Sintering of mechanically activated Zno-TiO2 powders
- 81 Downloads
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using dilatometry and SEM. The activation energy of sintering is determined using the method based on different heating rates and Dorn’s method as well. The phase composition of the isothermally sintered samples is determined using x-ray powder diffraction.
