    When the SiC powders with a larger particle size (44 μm) and the sintering aids were milled for 24 h, the particle size of the SiC powders was reduced due to the force of the ball mill. Therefore, the grain size (3.75 μm) of the sintered ceramic S1 is much smaller than the particle size of the initial SiC powders .
