TiO₂ Whisker Prepared with Tataniferous Blast-Furnance

Abstract:

Using titaniferous blast-furnace slag (44-70 wt %), quartz, boric acid, and borax as the main raw materials, composition selecting in the phase-separation region of the Na2O-CaO-Al2O3-B2O3 -SiO2-TiO2 system, the basic glasses were prepared through mixed batches and melted at 1200 oC, then TiO2 whiskers could be achieved by heat-treatment the glass samples. The phase and morphology of samples were analyzed by XRD and SEM. The results indicated: when the composition of samples were selected in the phase-separation region and the ratio of SiO2/ B2O3 was between 1.64-1.87, at 850 °C heat-treatment, the diameter of whiskers was about 0.5μ~1μ and the length-diameter ratio was more than 50.
