Optimisation of properties of silicon carbide ceramics with the use of different additives
The influence of different additions on the densification behavior of SiC based ceramics has been investigated. The SiC matrices reinforced by additives of amorphous B, Cr, Si were fabricated using High Speed Hot Pressing Method. Additives content was in the range from 0.5 to 3 wt. %. Microstructura...
