Sažetak

The internal structure of monodisperse barium. sulfate particles
precipitated from homogeneous solution was studied. The
elliptically shaped particles were examined by a sufficiently penetrating
electron beam (acceleration voltage 80 kV) and by the
ultramicrotomic technique. The particles did not appear compact
but had a sponge-like structure with an average pore size of 30 A.
The present results are supporting the assumption of barium
sulfate particles being possibly formed by an aggregation mechanism
predominantly over the direct diffusion growth of primary
particles.
