Influence of Pressure in Flash Sintering Technique

An innovative pressure-assisted flash-sintering technique has been developed to investigate the effect of pressure applied on microstructure and the sintering behavior of titanium dioxide. There are numerous applications for titanium dioxide in ceramics including microeletronics, glass ceramics, refractive materials, structural ceramics and titanium-containing ceramic materials and chemical intermediates. The traditional sintering of titanium dioxide usually requires several hours at over 1200 °C. The conducted research indicates that titanium dioxide can be sintered to full density in only a few seconds at 800-1000 °C, when subjected to a DC electrical field at a certain temperature moment.
