Sodium rare-earth silicate with Na₅DySi₄O₁₂ components is known as a highly conductive and stable sodium ion solid electrolyte though are difficulties in obtaining a single-phase, highly conductive Na₅DySi₄O₁₂ pellet because it has low conductivity impurity phases. In this study, microwave heating for aqueous solution of starting materials was performed for the formation of homogeneous precursor of Na₅DySi₄O₁₂. A single-phase Na₅DySi₄O₁₂ was successfully obtained from the aqueous solution heated with 2.45GHz microwave at 80 °C after calcination at 700 °C and sintering at 1050 °C. The Na₅DySi₄O₁₂ showed high conductivity of 2.9 × 10⁻⁴ at 30 °C and an activation energy of 0.25 eV. The precursor particles with microwave heating were fine particles with a narrower particle size distribution than those without microwaving. The results of thermal analysis showed different thermal behaviors with and without microwaves. The crystalline phase after calcination at 700 °C was different with and without microwave. After sintering at 1050 °C with microwaves was a single-phase Na₅DySi₄O₁₂, but the pellets without the microwaves heating process did not have a crystalline phase of Na₅DySi₄O₁₂. These results demonstrated that microwave heating of aqueous solution affects the formation of single-phase Na₅DySi₄O₁₂.

具有Na ₅ DySi ₄ O ₁₂成分的稀土硅酸钠被认为是一种高导电性和稳定的钠离子固体电解质，尽管由于其具有低导电性杂质而难以获得单相，高导电性的Na ₅ DySi ₄ O ₁₂颗粒是困难的阶段。在这项研究中，对原料的水溶液进行微波加热以形成Na ₅ DySi ₄ O ₁₂的均相前体。单相Na ₅ DySi ₄ O ₁₂在700°C煅烧并在1050°C烧结后，从在80°C下用2.45GHz微波加热的水溶液中成功获得γ-烯烃。Na ₅ DySi ₄ O ₁₂在30℃下显示出2.9×10 ^-4的高电导率和0.25eV的活化能。微波加热的前体颗粒是比无微波的颗粒具有更窄粒度分布的细颗粒。热分析的结果表明，在有和没有微波的情况下，其热行为都不同。在有和没有微波的情况下，在700°C下煅烧后的结晶相都不同。在1050°C微波烧结后，得到单相Na ₅ DySi ₄ O ₁₂但是，没有进行微波加热处理的粒料不具有Na ₅ DySi ₄ O ₁₂的结晶相。这些结果表明，水溶液的微波加热影响单相Na ₅ DySi ₄ O _12的形成。
