The invention relates to a method of preparing a titanium- and zirconium-based oxide. The inventive method consists in: forming a liquid medium which contains a zirconium compound and a titanium compound; subsequently heating said medium; and recovering the precipitate obtained at the end of the previous step and optionally, calcining said precipitate. The invention also relates to a titanium- and zirconium-based oxide. The oxide can contain between 30 and 40 wt.- % titanium oxide and in this case, said oxide presents a pure ZrTiO¿4?-type structure or a mixture of phases with ZrTiO¿4?-type structure and anatase-type structure. The aforementioned oxide can also comprise between 10 and 20 …

Why it's free to use
- Filed December 11, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 11, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 11, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
