The Study Of Tio2 Whiskers Prepared By Melt Phase-Splitting Method And Their Photocatalytic Properties

This paper studied the preparation of TiO2 whisker with melt phase-splitting method, which used tataniferous blast-furnance as the main raw maternal. XRD and SEM were used to research the phase and morphology of the sample, and by the same time, the photocatalytic properties of TiO2 crystal-beards was tested. The result have shown:the size of TiO2 crystal-beards was sub-micron rank, the crystal type was beta-TiO2 of orthorhombic high-pressure phase. The generation of TiO2 crystal-beards were effected mainly by the content of Na2O and TiO2, and the heat treatment temperature. The sample had certain photocatalytic properties and the highest photocatalytic efficiency was 56%.
