Study on physical properties of dispersed silica

摘要

The paper deals with the physical properties of colloidal silica dispersed system such as distribution width (Q_x, %) and density (q_x, %) defined by photon cross correlation spectroscopy (PCCS) at an average size of 17.06 nm for D_(50) % and the area of specific surface of 349.96 m~2 cm~(-3) depending on molar (R_(m2) optimal ratio of silica stone mineral to alkali ash powder. The change of crystal structure to amorphous state was determined by X-ray diffraction analysis. The results of their kinematic viscosity, liquid density, UV light adsorption inspections show possibility to produce the colloidal silica by using the wetting and ultrasonic vibration method for that fusible alloy.
