WebApr 2, 2024 · The calculated lattice constant “a” values found from both XRD data and fitting the Nelson–Riley function display noticeable reduction with an increase in Mn contents for x = 0.00–0.10 and then start to increase with further Mn addition. The decrease in porosity with an increase in the Mn content (up to 10%) reflects better crystallization.
