(a) A contour plot of the evolving diffraction peaks for maricite NaMnPO4 (m-NMP) synthesis with temperature. (b) Evolution of the refined weight fractions of the seven indexed phases. (c) Evolution of the average apparent size of m-NMP. (d) Results of the calculated profiles for a pattern where highly overlapped diffraction peaks exist and where broadening parameters are kept fixed (pattern number 45). The experimental X-ray powder diffraction pattern (blue curve) is compared with the calculated profile (red line). The black line denotes the difference curve between them and green vertical lines indicate the Bragg reflections corresponding to the five identified phases. Light-violet, light-green, red, dark-violet and purple patterns correspond to the calculated profiles of these phases. |
