适量的钡离子可以置换Ca2SiO4晶体中的Ca2+而形成固溶体,对原晶体结构并不产生显著的影响.光电子能谱测定结果表明,在钡固溶体中,氧的第一电子层中1S电子(O1s)和硅的第二电子层中2P电子(Si2p)的电子结合能向低能出现了化学位移.红外光谱测定结果也表明,硅氧键特征伸缩振动峰发生弥散,并向低波数方向移动.这些结果都说明,钡固溶体中部分硅氧键发生了驰豫。

An appropriate amount of Ca2+ in the Ca2SiO4 crystal can be replaced by Ba2+ to form a solid solution without exerting significant influence on the original structure of the said crystal. The combination energy of O1s and Si2p electrons shows a displacement to the lower energy region in the ESCA spectroscopy, and the vibration energy peak of Si-O bonds shows a displacement to the lower wavenumber region in the IR spectroscopy. All these results prove that there are some Si-O bonds relaxed in the barium-containing solid solution.
