摘要：

Single phase crystalline fine particles of the (Cr1-xTix)2O3 solid solution have been synthesized by vapor-phase explosive reaction of CrO2Cl2-TiCl4-H2 system ignited by a single laser pulse. The distribution of particle size was uniform with a mean particle size of 35nm. Lattice constants of the (Cr1-xTix)2O3 have been determined accurately by the Whole-powder-pattern decomposition (WPPD) method. The axes lengths of the hexagonal unit cell of the oxide increase linearly with increasing Ti mole fraction x. The c axis of (Cr1-xTix)2O3 has larger expansion than the a axis. The crystal structure of the (Cr1-xTi-x)2O3 was studied by the Rietveld analysis.
