Calcined Alumina Crystal Form Conversion Rate

 Al₂O₃ has many isomorphic crystals, with more than ten currently known. Different structures result in different properties of these isomorphic crystals. There are three main crystal forms in use: α-Al₂O₃, β-Al₂O₃, and γ-Al₂O₃. In the performance testing of α-Al₂O₃, one of the more important technical indicators is the α-phase transformation ratio. The α-phase transformation ratio represents the proportion of the α-phase in alumina products. Currently, both domestically and internationally, the α-phase transformation ratio of alumina is measured using the X-ray diffraction method.
