Av. Ignatchenko et al., STUDY OF THE FRACTAL STRUCTURE OF AGGREGATES BY THE METHODS OF SEDIMENTATION AND HYDROSOL RHEOLOGY, Colloid journal of the Russian Academy of Sciences, 54(4), 1992, pp. 485-488
A study is made of the rheological properties of dilute hydrosols cons
isting of aggregates of ultradisperse diamond particles (UDD). Data fr
om calculation of the degree of immobilization of the solvent by the U
DD aggregates is compared with data from sedimentation analysis. A met
hod is proposed to evaluate the fractal dimension, which was 2.1-2.3 f
or the UDD aggregates. An analysis of the dependence of the fractal di
mension on temperature, ionic force, and the pH of the medium showed t
hat a single mechanism is probably responsible for aggregation under t
he given conditions.
