Embodiment 1
[0026] Add 10 kg of deionized water to the reaction tank, take 500 grams of titanium tetrachloride and add it to the reaction tank for dilution to form an aqueous solution of titanium tetrachloride with a concentration of about 5%, slowly add ammonia water for neutralization reaction and white titanium hydrogen Oxide precipitates are precipitated, keep stirring and continue to observe the change of pH value, and stop adding ammonia water when the pH value is 7.0. After the above precipitate was filtered, cleaned and purified, about 300 grams of white titanium hydroxide was formed, and the titanium hydroxide was placed in a dispersion tank, and 878 grams of 50% concentration hydrogen peroxide was added to keep stirring and fully reacted, and 2.07 kg Add tetramethylsilane into the dispersion and stir fully, add 180 grams of oxalic acid into the dispersion and stir fully, add about 95 kg of pure water into the dispersion and keep stirring to fully disperse the hydroxide of titaniu...
Embodiment 2
[0029] Add 10 kg of deionized water to the reaction tank, take 5.5 kg of titanium tetrachloride and add it to the reaction tank for dilution to form an aqueous solution of titanium tetrachloride with a concentration of about 35%, and slowly add aqueous sodium hydroxide solution to neutralize and white titanium. The hydroxide precipitate precipitated out, kept stirring and continued to observe the change of the pH value, and stopped adding the aqueous sodium hydroxide solution when the pH value was 9.0. After the above precipitate was filtered, cleaned and purified, about 3.3 kg of white titanium hydroxide was formed, and the titanium hydroxide was placed in a dispersion tank, and 44.872 kg of potassium permanganate aqueous solution was added to the dispersion and fully stirred. Add 118.38kg of tetraethylsilane into the dispersion and stir fully, add 11.368kg of phosphoric acid into the dispersion and stir fully, add about 5220kg of pure water into the dispersion and keep stirri...
Embodiment 3
[0032] Add 9 kg of deionized water to the reaction tank, take 2.5 kg of titanium sulfate and add it to the reaction tank for dilution to form an aqueous solution of titanium sulfate with a concentration of about 20%, and slowly add aqueous potassium hydroxide solution to neutralize and precipitate white titanium hydroxide. Precipitate, keep stirring and continue to observe the change of pH value, and stop adding aqueous sodium hydroxide solution when the pH value is 9.0. After the above precipitate was filtered, cleaned and purified, about 1.2 kg of white titanium hydroxide was formed, and the titanium hydroxide was placed in a dispersion tank, and 6.936 kg of a 50% hydrogen peroxide aqueous solution was added to the dispersion liquid and fully Stir, add 29.43kg of tetraallylsilane into the dispersion and stir well, add 31.11kg of tetrapropylammonium hydroxide into the dispersion and stir well, add about 1495kg of pure water into the dispersion to keep Stir to fully disperse t...
