摘要
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.
FTIR is used to study the adsorption behavior of the precursor powder of Bisystem superconductor ground in atmosphere of air and argon respectively. The results show that grinding operation in air causes chemical adsorption of CO2 and H2O from air by the superconducting powder, while the same operation in Ar causes no chemical adsorption. The adsorption mechanism is analyzed by means of characterization of the crystal structure of Bi-system superconductor.
