  • Sintering of High‐Purity MagnesiaALLISON1956

    A marked decrease in the density of sintered (fired) compacts occurred when petro‐graphically identifiable periclase was formed in calcining. By employing proper heat‐treatment in calcining the powder ceramic bodies with zero apparent porosities were obtained at sintering

  • Microstructure and Density of Sintered ZnO Ceramics

    Three different sintered ZnO ceramics were prepared by magnetic pulsed compaction (MPC) and other conventional methods. The microstructures of the sintered ZnO ceramics prepared by MPC at sintering temperatures ranging from 900 to 1300°C showed a homogeneous grain growth compared to those of the samples prepared using other methods under the same sintering conditions.
