The Influence of Different Particle Size of Carbon Powders on the Preparation of Porous Silicon Carbide Ceramic
On the preparation of porous ceramics with composite sintering auxiliaries Y2O3-Al2O3 , the main ingredient of SIC , and CMC as the porous agent . Having studied the C content of composite structure and mechanical properties , And analysised the composite fracture morphology with SEM . The results show that, when using different particle size of carbon powders mixed the porous silicon carbide ceramic sample size powdered carbon than a single sample of micro skeleton intact, the shapes of holes, and more rules are uniformly distributed, comprehensive mechanics performance is better.
