2019-1-27 · The fracture strength of silicon carbide (SiC) plate deposits produced by Chemical Vapor Deposition (CVD) was determined from room-temperature to 1500 C using a standard 4-point flexural test method (ASTM Cl 161). CVD SiC materials produced by two different manufacturers are shown to have only slightly different flexural strength values, which appear to result from differences in microstructure.
