Question

Stable suspensions of Al2O3particles and SiO2 particles are prepared separately at a pH = 6. If the two suspensions are mixed, discuss the colloidal stability of the resulting suspension.

Answer 1

Generally, we get two know about the stability of the ceramic suspensions by Zeta potential and particle size measurement but most of the techniques know a days make use of the diluted suspensions and the concentrated solutions are no longer useful, when we pass through the light through a concentrated colloidal solution we can get to know the colloidal stability of the suspension. So we can study the stability of the colloid maintained at rest by multiple light scattering. In this way, we can understand the colloidal stability of the mixture of Al2O3particles and SiO2 particles
