Influence
of ultrasonication on the stability of an aqueous disperse system calcium
hydroxyapatite – Tween 80
Abstract
Effects of ultrasonication time and Tween
80 concentration on the stability of calcium hydroxyapatite aqueous suspensions
were studied. The optimal conditions under which the system becomes stable were
found using methods of capillary zone electrophoresis, dynamic light
scattering, and scanning electron microscopy. The possibility of estimating the
system stability was shown based on study of particles electrophoretic
behavior.
Key words:calcium hydroxyapatite, Tween
80, ultrasound, capillary zoneelectrophoresis,scanning electron microscopy,dynamic
light scattering.
