Summary:The rate of particle orientation for a colloidal processing in magnetic field was examined experimentally by the temperature dependence of viscosity of slurry. Slurry consisting （Sr, Ca）2NaNb5O15 particles and photopolimarization resin was used and consolidated by UV irradiation reaction after various duration times in the strong magnetic field. The degree of orientation of a sample increased with the duration time. Viscosity of the slurry decreased remarkably with an increasing in temperature from 20℃ to 50℃. The reduction of the viscosity of slurry contributed to make the hydrodynamic torque small, and the duration time in the magnetic field become short. In a magnetic field at 6 T, the time for sufficient orientation was achieved within 10 seconds in spite of using condensed slurry with 45 vol％. The result will contribute to spread this fabrication process.
