Method for preparing ortho silicic acid, ortho silicic acid as obtained, and its use

摘要

The invention relates to 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 under 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, food or feed supplement, and of a pharmaceutical or cosmetic preparation.
