Tartalmi leírás:
Barium sulfate particles
were prepared from BaCl2 and
Na2SO4 under various conditions to
explore their potential application
as contrast material in endovascular
surgery. Ethanol was added for
the stabilization of the suspension
obtained. Particle characteristics
of the samples were determined
by SEM and light scattering, while
the stability of the suspensions was
characterized by sedimentation
experiments. Particle characteristics
were shown to depend very much
on reaction conditions. Particles
were obtained in spherical and plate
like shape and in a variety of sizes.
Primary particles of nanometer size
formed aggregates in most cases.
Some of the samples had bimodal
particle size distribution. Particle
characteristics determined from SEM
micrographs, by laser light scattering
measurements and calculated
from sedimentation experiments
often differed from each other. The
discrepancy could be explained by
the dissimilar behavior of various
fractions and the different sensitivity
of the measurements to them. Some
of the samples showed aging phenomena
in DMSO leading either to
the formation of larger particles or to
the break down of aggregates.
