适量的钡离子可以置换Ca_2SiO_4晶体中的Ca~(2+)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IS电子(O_(1s))和硅的第二电子层中2p电子(Si_(2p))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。
Appropriate amount of barium ions can replace Ca2 + in Ca2SiO4 crystal to form a solid solution, which does not have a significant effect on the original crystal structure. The results of photoelectron spectroscopy showed that in the barium solid solution, the electron bond energy between the IS electron (O_ (1s)) in the first electron layer of oxygen and the 2p electron (Si_ (2p)) in the second electron layer of silicon appears to be low Chemical shift. The result of FTIR also shows that the characteristic stretching vibration peak of silicon oxygen bond diffuses and moves to the low wavenumber direction. All these results show that part of silicon-oxygen bonds in barium solid solution relaxes.
