Abstract

It is shown by IR spectroscopic investigation that ceramic zinc telluride contains water and carbon dioxide adsorbed on the surface of cavities between crystallites. It is found that hydroxyl groups occur on the surface of products as early as in the polishing stage, while the groups belonging to CO₂ are adsorbed during storage under normal conditions. It is also established by the photoluminescence method that mechanical fracture of ceramics manifests itself in the crystallite composition’s deviation from stoichiometry and narrowing of the band gap.

ZnTe陶瓷机械加工过程中微晶结构的杂质和本征畸变的光谱研究

摘要

通过红外光谱研究表明，陶瓷碲化锌包含水和二氧化碳，该水和二氧化碳吸附在微晶之间的空腔表面上。已经发现，早在抛光阶段，羟基就出现在产品的表面上，而在正常条件下的储存过程中，属于CO ₂的基团被吸附。通过光致发光方法还可以确定，陶瓷的机械断裂表现为微晶组成偏离化学计量和带隙变窄。
