In this paper, SiC particles of different particle sizes were used as aggregates to prepare SiC porous ceramics (50-70 mesh, 70-80 mesh and 80-90 mesh), and their flexural strength, filtration pressure drop and porosity were tested. On this basis, SiC with 80-90 mesh size was used as the aggregate, and the properties of porous ceramics were measured by using different proportions of pore-making agent. The results showed that when SiC particles were 80-90 mesh and the ratio of pore-making agent was 2:1, the samples prepared at 1300°C for 1.5h had the best comprehensive performance, the porosity was 33.9%, the flexural strength was up to 38.28MPa, and the filtration pressure drop was relatively low.
