The Effect of Al-powder as an additive on the Sintering of $Al_2O_3$ (II. In air,1600~180$0^{circ}C$)

ABSTRACT

As the effect of Al-powder as an additive on the sintering of $Al_2O_3$ was found satisfacotry in the range of 1350-155$0^{circ}C$ this experiment was carried out at higher temperature(1600-180$0^{circ}C$) at which the commerical $Al_2O_3$ body is sintered. Some phsical properties were measured and the micostructures of the specimens were observed by SEM. Although some measured physical properties of the specimens were improved through the addition of Al powder to $Al_3O_2$ powder the systematic changes in microsturces of the specmens could not be observed by SEM.
