چکیده انگلیسی
In this study, the Li2+xMg3SnO6 (LxMS) ceramic systems were prepared by solid-state reaction using novel atmosphere-controlled sintering (x = 0.00-0.12). The influences of extra lithium contents on the phase evolution, crystal structure and microwave dielectric properties of Li2+xMg3SnO6 (LxMS) ceramics were systematically investigated. As samples were calcined from 800 to 1000 °C, the Li2Mg3SnO6 phase was formed from the chemical reaction between Li2SnO3 and MgO phase. Pure Li2Mg3SnO6 phase could be observed for samples calcined at 1000-1100 °C. But when it was exposed to high temperature air over 1100 °C, the Li2Mg3SnO6 decomposed into Mg2SnO4, MgO and Li2O. Because of the protective atmosphere and extra lithium, the εr, QÃf and Ïf were significantly improved by the suppression of secondary phase and pores for 0.00â¤xâ¤0.08. However, comprehensive microwave characteristics were deteriorated for 0.08
