And the effect of nitrate additive on the densification of SiC-TiC composites was compared with that of Al2O3 and Y2O3 additives. Because nitrate additives were uniformly dispersed in SiC and TiC mixture, it inhibited the growth of crystal grain between each other and formed fine and uniform microstructure, thereby improving mechanical properties and electrical resistivity. The electrical resistivity and flexural strength of the SiC-TiC composite with aluminum and yttrium nitrate additive were 2.3 Omega.cm and 652.3 MPa respectively.eninfo:eu-repo/semantics/closedAccessSiC-TiCCompositesMechanical propertiesElectrical resistivityNitrate additiveArticleQ3Q321S16S22WOS:0005414303000033
