PARTICLE SIZE DETERMINATION OF THE METAL OXIDE SOLS BY ULTRACENTRIFUGATION
https://doi.org/10.15518/isjaee.2016.07-08.057-068
Abstract
In recent years, ultracentrifugation method was developed due to the growth of research in the field of nanotechnology. Ultracentrifugation is the most rigorous way to determine the molecular mass and hydrodynamic properties of macromolecules and colloidal particles. This method is applicable to both organic and inorganic substances, strictly speaking, to any substance whose optical properties a the ultracentrifugation method to metal oxide sols, experiments were conducted to determine the particle size of silicon oxide SiO2 and zirconium oxide ZrO lows calculating the average size of sol particles, but also determining the shape of the particle size distribution function in the test sol.
