The Study of TiO₂ Whiskers Prepared by Melt Phase-Splitting Method and their Photocatalytic Properties

Abstract:

This paper studied the preparation of TiO₂ whisker with melt phase-splitting method, which used tataniferous blast-furnance as the main raw materrial. 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 wasβ-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%.
