Abstract
A quantitative phase analysis device for analyzing non-crystalline phases comprising at least one microprocessor configured to: acquire the powder diffraction pattern of the sample; acquire information on one non-crystalline phase and one or more crystalline phases contained in the sample; acquire a fitting function; execute whole-powder pattern fitting, acquire a fitting result; and calculate a weight ratio of the one non-crystalline phase and the one or more crystalline phases. The fitting function for each of the one or more crystalline phases is one fitting function selected from the group consisting of a first fitting function that uses an integrated intensity obtained by whole-powder pattern decomposition, a second fitting function that uses an integrated intensity obtained by observation or calculation, and a third fitting function that uses a profile intensity obtained by observation or calculation. The fitting function for the one non-crystalline phase is the third fitting function.
