Silicon carbide test bars were made by a simple wet‐processing technique. The pressure casting method used the same equipment as conventional dry‐pressing, but with a modified die. This casting technique was employed in order to produce test bars with improved strength and smaller fracture flaws than produced by dry‐pressing. This was accomplished by eliminating pore clusters which were present in dry‐pressed specimens and identified as a common source of failure in SiC MOR test bars.
