Abstract

A quantitative X-ray diffraction method for the phase analysis of fertilizers of the NPK 12-19-19 type has been worked out together with a complex system of computer software. A bank of synthetic standards was employed in the solution of the problem. To reflect the real structure of the phases determined in fertilizers as against the structure of synthetic standards, intensity coefficients based on chemical analyses were assigned to individual phases in the bank of standards.
