Notes:
One-thousand gamma particles in spherical amalgam and 1000 spherical gamma particles embedded in resin were sectioned, and the diameters for the sections were measured. Microhardness determinations were done on 50 particle sections in amaglam containing 46% mercury, 50 sections in amalgam of 52% mercury, and 50 sections of nonamalgameted particles embedded in resin.The gamma particles in amalgam seemed to have expanded as a result of their uptake of mercury. The gamma particles in amalgam had a lower hardness than the nonamalgamated particles embeded in resin. The hardness values ofthe particles were not statistically different in amalgam comtaining 46 and 52% mercury.
