Class Information
Number: 516/85
Name: Colloid systems and wetting agents; subcombinations thereof; processes of > Continuous liquid or supercritical phase: colloid systems; compositions an agent for making or stabilizing colloid systems; processes of making or stabilizing colloid systems; processes of preparing the compositions (e.g., micelle; thickening agent; protective colloid agent; composition containing an emulsifying agent with no dispersant disclosed; organic liquid emulsified in anhydrous hf) > Aqueous continuous liquid phase and discontinuous phase primarily solid (e.g., water based suspensions, dispersions, or certain sols*, of natural or synthetic ester-wax, beeswax, carnauba wax; or latex dispersion) > The solid is primarily inorganic material (e.g., mercurous halide) > The material primarily contains compound containing silicon covalently bonded to oxygen (e.g., aluminum silicate, clay) > The material is substantially pure silica sol > Gel forming step (e.g., peptize)
Description: Subject matter in which said substantially pure silica is prepared by a process which employs a gel forming step, such as, to peptize the reactants.
