Method for Preparing Ortho Silicic Acid, Ortho Silicic Acid as Obtained, and its Use

摘要

A method for preparing ortho silicic acid wherein an acid hydrolysable silicon compound is hydrolysed in an acid solution in the presence of a non-toxic solvent agent resulting in the formation of ortho silicic acid, wherein preferably the ortho silicic acid formed is contacted with a non-toxic particulate carrier, and to the use of a silicon preparation in the production of animal feed, food or food supplement, and of a pharmaceutical or cosmetic preparation.
