Abstract

The invention relates to the inorganic chemistry. A process comprises hydrolysis of silicone tetrachloride in acid followed by precipitate filtration, washing and calcination. The hydrolysis is carried out in 15-20% hydrochloric acid at molar ratio of SiCl44HCL=1H(2-2.5) in the presence of silicon nuclei SiO22X H2O , wherein X=0.3-0.5, taken in quantity of 1-2 % related to SiO2 in solution.
