In this article low temperature sintering of mechanically activated BaCO3-TiO2 system was studied. A stoichiometric mixture of BaCO3 and TiO2 powders was mechanically activated in a high-energy vibromill for 0, 30, 90 and 180 min, calcined at 800oC for 1 h and reaction sintered at 1100oC ...
increasing. At the same sintering temperature, higher electrolysis temperature was helpful for the generation of titanium. The current decreased as the time increasesed in electrolytic process; the increase of the electrolysis temperature is favorable to the generation of the titanium. However, ...
Spark plasma sintering (SPS) of an Al2O3-ZrSiO4 mixture of fine powders in the presence of TiO2 as an additive, which supplies a transient liquid during firing, has been studied. The effect of the sintering temperature, as well as the presence of the additive on the phase's evolution, ...
The effect of sintering temperature on the boundary segregation and dielectric properties of several (Ba, Nb)-doped TiO 2 ceramics was investigated. Koops equations are used to explain the dispersive dielectric properties and to study the boundary segregation. Calculated results of the thickness of ...
