Using your own wordarrow_forwardIn a research lab where ceramics are heat treated for further application, you are presented with two unlabelled specimens (A, B) of bio-ceramics and told that they have the same basic chemical composition, but one has been sintered properly and the other has not been sintered at all. Sample A has larger pore size, and somewhat smaller grains than Sample B. If all ceramics have to be heat treated, which of the specimens need to go into the furnace? Select one: a. Sample A to go into furnace O b. Neither Sample A nor B to go into the furnace O c. Both Samples A and B to go into the furnace Od. Sample B to go into furnacearrow_forward

A by-product of this substitution, however, is mass reduction.
