Initially SiC particles before milling are spherical in shape and uniform in sie and appear dull in color as shown in a. Ball milling of SiC particles carried out in wet milling arrangement by using toluene as a process control agent milled samples for FESEM analysis has been conducted in regular interval of time
201952ZrCSiC ceramics were fabricated by highenergy ball milling and reactive hot pressing of ZrH2 carbon black and varying amounts of SiC. The ceramics were composed of nominally pure ZrC containing 0 to 30 vol SiC particles
A new method of sintering diamondsilicon carbide composites is proposed. This method is an alternate to the liquid silicon infiltration technique and is based on simultaneous ball milling of diamond and silicon powder mixtures. Composites with finegrain diamonds embedded in a diamondSiC nanocrystalline matrix were sintered from these mixtures
