摘要： A method for measuring degree and homogeneity of calcination of alumina utilizing an image analysis device equipped with a sensitive camera in a spectral analysis window corresponding to a wavelength range equal to or in the vicinity of visible light. The method includes the steps of mixing alumina under analysis in a liquid wherein the refractive index is, in the wavelength range, between the refractive index of a lightly calcined alumina and the refractive index of a strongly calcined alumina, preparing a slide for observation of the mixture in the image analysis device, the mixture being illuminated by stable polychromatic radiation compatible with the spectral analysis window, receiving an image by the camera and processing a signal resulting in the definition of an image composed of a given number of pixels with three calorimetric components, and statistically processing the pixels using their calorimetric components and determining the calcination degree and the homogeneity of the calcination.
