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
