非晶态Li~+导体B_2O_3-0.7Li_2O-0.7LiCl-0.1Al_2O_3在等温处理过程中,其电导率先随时间升高,出现峰值后下降,随后出现两个平台。这是由于材料的分相和晶化所致。本文据相界效应观点,认为不同相之间界面附近有一高电导率层,它对电导率的贡献补偿和超过了由于分相和晶化的体效应所引起的电导率下降。由此,对这种材料的电导率随时间变化曲线给出了解释。
The conductivity of amorphous Li ~ + conductor B_2O_3-0.7Li_2O-0.7LiCl-0.1Al_2O_3 increased with time, peaked and then decreased, followed by two platforms during the isothermal treatment. This is due to the phase separation and crystallization of the material. In this paper, according to the concept of phase boundary effect, it is considered that there is a high conductivity layer near the interface between different phases, which contributes to and compensates for the conductivity and compensates for and exceeds the decrease in conductivity caused by the bulk effect of phase separation and crystallization. Thus, the conductivity of this material over time curve is given an explanation.
