실험 절차

Into a reactor equipped with a stirrer, a thermometer and a condenser, 900 kg of water, 7.0 kg of silica hydrosol (SiO2 concentration: 14.4%, Al2O3 concentration: 0.57%, particle size: 5 nm), 50 kg of a melamine powder having an average particle size of 40 μm and a specific surface area of 0.8 m2 /g and 51.2 kg of a cyanuric acid powder having an average particle size of 50 μm and a specific surface area of 0.6 m2 /g were introduced with stirring and then mixed under heating at 85° C. for 2 hours to obtain an aqueous dispersion slurry having a slurry viscosity of 1300 mPa.s. Then, the slurry was dried by a spray dryer manufactured by Ashizawa Niro Atomizer K.K. at an inlet temperature of 270° C. to obtain a melamine cyanurate powder having a bulk density of 0.38.
