【摘要】 对非晶态 Li⁺导体 B₂O₃—0.7Li₂O—0.7LiCl—0.1Al₂O₃在300℃温度下分相和晶化过程进行了扫描电镜（SEM）观察。结果表明;在等温处理的开始阶段,样品内首先发生分相,从母相中分离出均匀分布的新的非晶相粒子,随后长大和聚集;然后,新非晶相发生晶化长成晶粒,其成分为 Li₄B₇O₁₂Cl;最后,背景的非晶相中析出另一种晶粒,成分为 LiBO₂,并有较大的生长速度。更多还原

【Abstract】 The phase separation and crystallization process at the temperature 300℃ in anamorphous Li⁺ conductor B₂O₃-0.7Li₂O-0.7LiCl-0.1Al₂O₃ have been observed withscanning electron microscope（SEM）.The result shows that the amorphous phase separa-tion occurs at the initial stage of the isothermal treatment process,and the distributionof the new amorphous phase particles separated from the original phase is even.Enlargement and connection of these new amorphous phase particles thus follow.After-wards,the crystallization of the new amorphous phase occurs and the crystallized grainswith the composition of Li₄B₇O₁₂Cl grow up.At last,another crystalline grain withthe composition of LiBO₂ is also separated from the amorphous phase at the background.They can grow with faster speed.更多还原
