| Outline of Final Research Achievements |
Crystalline spheres of composite compound were obtained with a pulsed laser irradiation of a binary particle mixture dispersed in liquid. A chemical composition of formed composite compound by a laser irradiation of a mixture of TiO2 and MgCO3 was only MgTi2O5 even at any mixed composition ratio. Although TiO2 can melt by laser irradiation with 355 nm wavelength, MgCO3 remains as a solid state due to an optical transparency. In contrast, FeB and Fe2B formation occurred with a laser irradiation of mixture a-Fe2O3 and B4C, in which phase transitions to liquid phase of both a-Fe2O3 and B4C was necessary. Thus, a composite compound sphere formation mechanism depends on materials of raw particle mixture in this technique.
