Latest Patents

Sergio Pieri holds a patent for the "Preparation of anatase titanium dioxide." This patent describes a process for preparing anatase titanium dioxide by precipitating hydrous titanium oxide in the absence of added nuclei from a solution of titanium sulphate. The solution contains the equivalent of 200 to 300 grams of TiO₂ per liter, with an acid to titanium ratio ranging from 1.6:1 to 2.2:1. The precipitation is induced by adding 5 to 35 parts of water per 100 parts of titanium sulphate solution. The hydrous titanium oxide is then calcined in the presence of a potassium compound and phosphorus, resulting in anatase titanium dioxide with an average crystal size larger than conventionally prepared anatase.
