Effect of Particle Morphology on Sinterability of SiC- in Microwave
Figure 7
The vickers hardness of non-milled powder mixture (heterogeneous) and milled powder (homogeneous) particle morphology of SiC-ZrO2 sintered by microwave and conventional electric furnace. The lower hardness of specimen sintered by conventional electric furnace compared with that sintered by microwave indicates that the sintering ability of SiC-ZrO2 in electric furnace is also very low, regardless of grain size and/or particle morphology.
