    摘要: This invention relates to azirconium solution or sol comprising:(a) zirconium,(b) nitrate, acetate and/or chloride ions, and(c) one or more complexing agents being an organic compound comprising at least one of the following functional groups: an amine, an organosulphate, a sulphonate, a hydroxyl, an etheror a carboxylic acid group,wherein the molar ratio of components (a):(b) is 1:0.7to 1:4.0,the molar ratio of components (a):(c) is 1:0.0005 to 1:0.1, and thepH of the zirconium solution or sol is less than 5. The invention also relates to a process for preparing a zirconium solution or sol, the process comprising the steps of:(a)dissolving a zirconium salt in nitric, acetic and/or hydrochloric acid, and(b)adding one or more complexing agents to the resulting solution, the one or more complexing agents being an organic compound comprising at least one of the following functional groups: an amine, an organosulphate, a sulphonate, a hydroxyl, an etheror a carboxylic acid group, and (c)heating the solutionor solto a temperature of at least 75°C. In addition, the invention relates to products formed from the zirconium solution or solor obtainable by the process.
