Particle size analysis of lanthana-doped yttria powders by automatic image analysis (IA) has been used to improve the quality of sizing data obtained using classical laser light scattering methods. A calibration test using monomodal, standard polystyrene spheres confirmed that the IA method provides a narrower distribution and improved size resolution compared to that obtained by light scattering. To ensure that the light-scattering distributions obtained in a study of lanthana-doped yttria powders were accurate, image analysis methods were used to obtain particle size distribution data from which corrected parameters for data reduction of the light-scattering data were obtained. In one case, a bimodal distribution obtained by light-scattering data was found to be artifactural when compared to the distribution obtained from IA measurements. It is concluded that direct particle size distribution analysis by image analysis can be successfully applied in light-scattering studies of yttria powders an... |
