Latest Patents

Curran M Simpson holds a patent for the "Preparation of silica sol." This invention describes a method for producing a silica sol that contains less than 200 ppm sodium, with an average particle size ranging from 2 to 110 nm. The particle size distribution is characterized by a coefficient of dispersion between 0.16 and 0.4. The process involves using a lower alkanolamine containing heel, to which aliquots of silicic acid are added. These aliquots are introduced to maintain a substantially constant concentration of colloidal silica in the final product. After production, the sol can be concentrated through ultrafiltration. The preparation technique emphasizes low sodium silica sol utilizing a constant silica method by heating the initial heel to 94 ± 4 degrees Celsius and adding additional silica to maintain a constant total silica concentration. Stabilization is achieved with an alkanolamine.
