Mechanical activation strongly influences the sintering of pressed articles made of a powdered titanium-nickel alloy and its compositions with dental porcelain. Preliminary treatment of the powdered mixtures in a planetary ball mill suppresses the martensite transformation and removes anisotropy in the variation of linear dimensions of the pressings. The resulting samples exhibit, instead of a

The entirely accidental observation of increased sintering performance of nickel-infiltrated yttria-stabilized zirconia (8YSZ) in a molybdenum and oxygen rich atmosphere was explored. Molybdenum and nickel were found to be synergistic sintering aids for 8YSZ. However, sintering had to take place in an atmosphere of flowing oxygen. Samples sintered in air consistently burst
