What term describes the process of converting remains into fine particles post-cremation?

The correct term for the process of converting remains into fine particles after cremation is pulverization. During cremation, the body is exposed to high temperatures, reducing it to ashes and bone fragments. Following this process, pulverization involves mechanically breaking down any remaining bone fragments into a uniform, fine powder. This ensures that the remains are more manageable and can be easily placed in an urn or memorialized in other ways.

The other terms listed do not accurately reflect this specific process. Dusting and grounding typically refer to actions that do not pertain to the treatment of cremated remains. Fragmentation may suggest breaking apart items but lacks the precision and context specific to the final processing of remains after cremation. Therefore, pulverization is the term that best captures the complete transformation of cremated remains into fine particles.
