Alpha-silicon carbide powder consolidated by both dry and wet methods. Dry pressing in a double-acting steel die yielded sintered test bars with an average flexural strength of 235.6 MPa with a critical Saw size of≈100m̈m. An aqueous slurry pressing technique produced sintered test bars with an average flexural strength of 440.8 MPa with a critical flaw size of≈25m̈m. Image analysis revealed a reduction in both pore area and pore size distribution in the slurry-pressed sintered test bars. The improvements in the slurry-pressed material properties are discussed in terms of reduced agglomeration and improved particle packing during consolidation.
