Abstract
1-x(Li2O–2P2O5)-xMnO2 glasses where x = 0.2, 0.3 and 0.4 mol%, respectively, were synthesized by melted-quenching method. The Mn and P oxidation states and local structures around Mn and P-ions including Mn–O and P–O bonding distances and coordination numbers have been studied via X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS), respectively. XANES results exhibit a coexistence of oxidation state of Mn2+ and Mn3+ with a mean value of 2.82. Moreover, Mn and P K-edge EXAFS show the Mn–O and P–O bonding distances of approximately 2.083–2.094 Å and 1.766–1.774 Å, respectively. A paramagnetism was found for all Mn–P glasses. Additionally, the coercive field (Hc) and remnant magnetization (Mr) increased with increasing Mn contents. However, the low specific capacitances are seriously obtained (<40 F g−1) suggesting the effect of natural diamagnetism of lithium phosphate based-glass unlike the borate based-glasses which originally exhibit paramagnetism. © 2021 Chinese Materials Research Society
