The PC articles made by compaction of crystalline powder
at 210[degrees]C showed a remarkable change in properties, arising from the low level of crystallinity.
Although calcination temperature of 1300[degrees]C is sufficient enough to produce high crystalline powder
with equiaxed morphology, the presence of irregular particles indicates that calcination time needs to be extended to allow for homogeneous temperature distribution throughout the NiO/Ni[Al.
