The powder obtained had a mean particle size 0.78-mu-m and a very narrow particle size distribution. The total porosity of the powder was estimated to be about 63%. It was found that much agglomeration had occurred among the droplets, which would have an adverse effect on the particle size distribution. The bulk density of a sintered specimen using the powder prepared at 950-degrees-C was higher than 97% theoretical density.
