摘要：

The crystalline and amorphous phases, excepting the gibbsite, from the samples collected at temperatures 120-160 degrees C have a low crystalline degree or at least are intensely eroded (being phases transported as small particles by the heating gases of the moist hydrate). As a result, quantitative determination of these phases in the samples collected at temperatures 120-160 degrees C proved to be a difficult problem, even if the measuring instrument is an advanced one and the Rietveld finishing program has been applied. The paper describes a method of identifying and characterizing these phases and provides information about this grade of alumina hydroxide availability and marketability.
