Lately a great attention is spared development of materials, possessing high stable dielectric properties. Among such materials a considerable place is occupied by titanates of metal series, including titanate of magnesium. ...

Starting mixtures of BaCO3 •ZnO and Ti02 were mechanically activated for 0,5, 10,20.40 and 80 minutes in a planetary ball mill. The powders obtained were sintered isothermally to temperatures between 1000 and 1300 °C. The ...

Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...

The aim of this work was to analyze influence of mechanical activation on MgO-TiO2 system. Mixtures of MgO-TiO2 were mechanically activated for 0, 5, 10, 20, 40, 80 and 120 minutes in a planetary ball mill and after that ...

Three-component oxide mixture was prepared containing MgO+Al2O3+SiO2 in a 2:2:5 ratio with addition of 10% Bi203. Mixtures were mechanically activated in range from 5 to 240 minutes in a mill with ceramic balls, and sintered ...
