1. Construction of fabrication apparatus of ceramics powders by mist-pyrolysis The apparatus consists of mist generator utilizing an ultrasonic neblizer (f =1 MHz) and an upright type electric furnace with a reaction tube of about 1 meter. The starting materials were the solutions of nitrates of the constituent metal ions dissolved in distilled water. The ion concentration in the solution,C_N was changed from 0.0001 to 0.1(mol/liter). The carrier gas was nitrogen or oxygen (or mixture of both gases). Main results are summarized as follows: (1) The deviation of composition occurs between the starting solution and the produced particles: The reduction of metal ion in the particles is determined by the ion mass irrespective of C_N. (2) The particle size a depends strongly on C_N according to the relation lna=AlnC_N +B, A, B: positive constants. (3) The produced particles were not substantially influenced by the flow rate of carrier gas unless the rate was very small.2. Fabrication of magn … More etic oxide powders by mist-pyrolysis. The following particles having a= 0.07-0.5 mum were successively produced.

Preparation of Bi-substituted YIG (and DylG) films by gel-coating on substrates. (1) Single crystal films with highly Bi substitution (x =2.7 f.u.) were obtained at 530ﾟC by coating the gels on GGG single crystal substrates. (2) The magneto-optical Faraday spectra can be explained by adding the contributions of the paramagnetic type transitions to those of the diamagnetic transitions in the foregoing theory based on the charge transfer transition.4.
