Bi系超导体原始粉末的化学吸附行为

用傅氏变换红外光谱（FTIR）研究了不同方法制备的Bi系超导体原始粉末研磨过程中；自环境气相中的化学吸附行为．结果表明；在空气中研磨，粉末化学吸附空气中的CO2和H2O在氩气中研磨则无化学吸附现象．用Bi系超导体晶体结构的特征分析了吸附机理.     

Effects of ZrO_2 on the Microstructure of a Mica Glass-ceramic

1 INTRODUCTION Glass-ceramic technology is based on the controlled nucleation and crystallization of glass, and glass-ceramics have several advantages over the conventional powder-processed ceramics. In addition to the easy flexibility of formation in t…
