| Abstract: | Two kinds of methods were used to make porous SiC ceramics .The effect of microstructure on the properties was discussed.A new technique was developed to make porous SiC from natural wood.The results showed that natural wood was good material for making porous SiC ceramics with high porosity more than 40%.Through this way,the prepared silicon carbide has high porosity ,shape-regular and well-distributed pores. |
