Abstract:Silicon nitride powder was prepared by combustion synthesis with silica fume. The effects of solid content, ultrasonic time, dispersant concentration and settling time on the particle size measurements were investigated by using median particle diameter d50 and particle diameter distribution width d90?d10 as evaluation indications. The results indicated that the laser particle size analyzer was applicable to measurement particle size of silicon nitride powder by combustion synthesis showing high reproducibility. The above four factors influenced significantly on the measurement results. When solid content was 1.25 g/kg, the needed ultrasonic time was 60 min, and dispersant content was 3 g/g, optimum dispersion results of Si3N4 by combustion synthesis can be achieved using water as the dispersing medium. In addition, the particle size measurement was the most reliable within 0.5 h after ultrasonic treatment.
