    摘要： A method for producing an active silicic acid solution in which the existing amount of foreign matters as plate-like fine particles is reduced and a method for producing a silica sol in which such foreign matters are reduced. The method fulfills the following condition: the existing amount of plate-like fine particles having a length of one side of 0.2 to 4.0 μm and a thickness of 1 to 100 nm is measured to be 0% to 30% in accordance with measuring method A, the method including the steps of: preparing an active silicic acid solution by subjecting an alkali silicate aqueous solution having a silica concentration of 0.5% by mass to 10.0% by mass to cation-exchange to remove alkaline components; and filtering the active silicic acid solution through a filter whose removal rate of particles having a primary particle size of 1.0 μm is 50% or more.

    摘要： Colloidal silica aquasols containing about 200-675 ppm 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride; 100-350 ppm 1,2-benzisothiazolin-3-one; or 160-800 ppm of 1,3,5-triazine-1,3,5 (2H,4H,6H)-triethanol are protected from contamination by microorganisms which cause undesirable changes in physical properties. This treatment prevents discoloration, bad odor and slime formation and increases the shelf life of colloidal silica sols to more than one year.

    摘要： IN THE STABILIZATION OF HOGHLY CONCENTRATED SOLS OF THE SILICA TYPE RANGING FROM 35-59% CONCENTRATION, WHICH HAVE BEEN SUBJECTED TO SEQUENTIAL DOUBLE DEIONIZATION THROUGH CATIONIC AND ANOINIC BEDS, THE ADDITION TO THE SOL OF A SMALL AMOUNT OF AN ANOIN OF AN INORGANIC ACID AMOUNTING OT 0.01 TO 0.15 WEIGHT PERCENT OF THE ANION BASED UPON A 50% SILICA SOL PRODUCT. THE SPECIFIC ANION IS SELECTED FROM SULFURIC, PHOSPHORIC, HYDROCHLORIC, AND NITRIC AND IS ADDED DIRECTLY OR OBTANIED BY UTILIZATION OF IMPURITIES IN THE SILCA SOL AND OMISSION OF ANION BED TREATMENT. THE STABILIZATION EFFECTIVELY PREVENTS GELATION DURING SUBSEQUENT ALKALIZATION AS IN THE PREFERRED AMMONIATION.
