【摘要】 文章应用固体与分子经验电子理论计算了镓酸镧基固体电解质材料的价电子结构,计算结果表明,1/(nAnB)随x及y增加而增加。实验结果表明,当x、y小于20%时,电导率σ随x、y增加而增加,并随1/(nAnB)增加而电导率σ增加,通过价电子结构的计算,可预测不同成分的LSGM的电导率。更多还原

【Abstract】 The valence electron structures of Sr-and Mg-doped LaGaO₃ ceramics with different compositions were calculated by using the empirical electron theory（EET）of solids and molecules.The results of calculation show that 1/（n_An_B）increases with increasing of x and y.The results of experiment show that conductivity increases with increasing of x and y when x andy are less than 20%,and that conductivity increases with increasing of 1/（n_An_B）when x and y are less than 20%.Therefore the conductivity of LSGM with different x or y can be forecast by calculating valence electron structures of LSGM.更多还原
