Abstract
The experiments using available indigenous raw materials have resulted in fixing conditions
for the preparation of zirconia-alumina abrasive materials. SEM photographs of typical samples
of zirconia-alumina have been taken and the hardness of the samples determined with aRockwell hardness tester. The microstructure enables evaluation of the grain shape which in
turn controls the abrasive operation to be used viz cutting, grinding or lapping. The hardness
values indicate the toughness of the grain.
