    摘要： The present invention relates to a method for forming a silica-based particle or composite consisting of a silica-based material, an active, with or without a surface modification, and the related composition. The silica-based particle is illustrated by the formula (SiO2)x(OH)yRzSt, whereby R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, and water soluble agents and, optionally, a surface modifier, S, which may be either organic, polymeric, or inorganic. Examples of a surface modifying material are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers. As such, the particle can be used in a variety of applications including any of a variety of high temperature, at acidic, neutral, or basic pH, or pressure environments. The composites have applications as diverse as papermaking, water treatment, chemical tracing, personal care, microbiological control, and delivery of polymers, for example. With regard to papermaking, the particle provides retention and drainage performance while delivering whitener, or OBA, other functional additives and serves an additive tracker.

    摘要： Methods of forming a silica-containing products are disclosed. One method comprises: (a) providing a silica containing precursor (SCP) contained in solution that has a pH less than or equal to a pH of 7; (b) optionally doping the SCP with one or more metal species; (d) adding an effective amount of salt to the solution so that the conductivity of the solution is greater than or equal to 4 mS; (e) optionally filtering and drying the SCP; and (f) optionally reacting the dried product from step e with a functional group. Another method comprises: (a) providing a silica containing precursor (SCP) contained in solution that has a pH greater than 7; (b) adjusting the pH of the solution to less than or equal to 7; (c) optionally doping the SCP with one or more metal species; (d) adjusting the pH of the solution to greater than 7; and (e) adding an effective amount of salt to the solution so that the conductivity of the solution is greater than or equal to 4 mS; (f) optionally filtering and drying the SCP. The SCP is then added to a hygroscopic solid such that the resulting product comprises a metal oxide-doped or metal sulfide-doped silica-containing product deposited on a substrate selected from hydrated alkaline earth oxide, lanthanide oxide, and combinations thereof.
