Preparation and Immobilization of Ti-based Oxides by Detonation Method

Abstract

Ti-doped gel, prepared by hydrolysis of tetrabutyl titanate and ammonium nitrate solution, was mixed with hexogen to make mix explosive. The mix explosive was detonated in a closed kettle in cylindrical charge with presence of aluminum plate, and then Ti-based oxides were fabricated. The samples were characterized by XRD, TEM, EDX, and SEM. The results showed that samples contained FeTiO 3 , a few of rutile, anatase, and Al 2 O 3. The Ti-based oxides particles were spherical in micrometer level scale. Ti-based oxides were successfully immobilized on an aluminum plate driven by Ti-contained detonation wave, and the size of particles on the plate was 10 μm. The present results suggest that the detonation method provides an easy way to prepare Ti-based oxides and fabricate particle-plate structure for recycling materials synchronously.
