【摘要】 木文研究了Al₂O₃对B₂O₃-0.7Li₂O-0.7LiCl非晶态的形成和电学性能的影响,我们发现:加入适量的Al₂O₃后,无需借助液氮骤冷技术,直接将熔体倾倒在室温下的紫铜板上就很容易形成大块非晶锂离子导体B₂O₃-0.7Li₂O-0.7LiCl-xAl₂O₃。 Al₂O₃的加入使B₂O₃-0.7Li₂O-0.7LiCl的电导率有所降低,但在高温下不太明显,电导激活能略微升高,实验发现:Al₂O₃含量x=0.03是较合适的剂量,较容易形成大块非晶态,对电导率的影响也不大。更多还原

【Abstract】 The effect of additive Al2O3 on both the formation of amorphous B2O3-0.7Li2O-0.7LiCl and it’s ion conduction property have been studied. It has been found that rather large slab of amorphous material could be easily prepared by pouring directly the melt contained suitable amount of additive Al2O3 onto a copper plate at room temperature without using liquid nitrogen.The additive A12O3 decreases slightly the conductivity of amorphous B2O3-0.7Li2O-0.7 LiCl but in high temperature range this effect is far less obvious because of the activation energy for the amorphous containing Al2O3 is slightly larger than that of pure one. It has been shown that Al2O3 = 0.03 is the optimum content which makes the preparation of amorphous more easily and dose not seriously influence the conductivity.更多还原
