用腐蚀法观察了五磷酸镧钕晶体的腐蚀缺陷。晶体中存在着錐形蚀坑和相应的腐蚀隧道及两种腐蚀沟槽。对这些腐蚀缺陷的形态、特点及分布进行了总结,并探讨了它们的产生与生长条件的关系,讨论了它们的成因及本质。
Etch method was used to observe the corrosion defects of lanthanum pentaphosphate crystals. There are conical pits and corresponding corroded tunnels and two kinds of corrosion trenches in the crystal. The morphology, characteristics and distribution of these corrosion defects are summarized, and the relationship between their production and growth conditions is discussed, and their causes and essence are discussed.
