132 石炭灰と粘土を複合化させた焼結体の機械的性質(OS 粉末加工(2))

Composite material using coal ash and clay were investigated in terms of mechanical property. From the schrinkage to the mold dimention, the optimum sintering temperature were determined with changing the firing temperature. Adding the clay amount to fly ash, the effect on shrinkage and the micro vickers hardness were investigated. As a result, because of clay melting phenomena beyond the 1473K, the sintering process during ash particles occurs on smoothing, and the hardness increases by clay amount. Composite material of ash, clay and sludges were drasticaly improved on the hardness at firing temperature 1673K.
