The mean particle diameter of a powder was measured by diffuse reflectance infrared Fourier transform (DRIFT) spectrometry, using a calibration curve relating the spectral intensity, plotted in Kubelka-Munk units, to the mean particle diameter. The particle sizes of three commercially available Si[sub 3]N[sub 4] powders were determined, using the calibration curve. The analytical results agreed well with the results obtained with a light diffraction and scattering particle counter, i.e., a microtrack analyzer, only with the two powders which had a narrow particle-size distribution. The method can, thus, be used to determine the mean particle size of the Si[sub 3]N[sub 4] in an Si[sub 3]N[sub 4]-alumina mixture.
