Manufacture of a titanium compound structure and a structure
The present invention relates to a method for manufacturing a structure of a titanium compound selected from the group consisting of sheets, wires and tubes. Titanic acid is dissolved in an acid below pH 1, TiO2 particles are formed by addition of a stabilizer and precipitation by heating to 68-85°C...

| description | The present invention relates to a method for manufacturing a structure of a titanium compound selected from the group consisting of sheets, wires and tubes. Titanic acid is dissolved in an acid below pH 1, TiO2 particles are formed by addition of a stabilizer and precipitation by heating to 68-85°C and stirring, an alkali metal hydroxide is added followed by treatment at 90-170°C during 6-72 hours, then the alkali metal ions are exchanged with protons. The present invention also relates to intermediate products and structures comprising titanium dioxide obtainable by the method. The invention provides an improved method giving improved yield as well as other advantages. |
