KDP晶体中链状分布液相包裹体形成机制分析

Analysis of Formation Mechanism of Chainlike Distribution Solution Inclusions in KDP Crystals

利用光学显微镜和扫描电镜(SEM)观测了KDP晶体中出现的一种呈链状分布的液相包裹体,发现它们的尺寸从几个微米到几十个微米不等,主要沿晶棱方向排列。对这类包裹体的形成条件和形成机制分析发现,它们的形成与近年来新提出的KDP晶体棱边生长机制有关,讨论了KDP晶体生长过程中出现生长机制的可能原因。

A kind of chainlike distribution solution microscopy and SEM. The size of these inclusions was arranged along the crystal edges. inclusions in KDP crystals were observed by from several to dozens of microns. They mainly With analyzing the formation conditions and mechanism of these solution inclusions, the relationship between their formation and the mechanism of growth from the edges, which new developed in recent year, was found. Possible reasons of inducing the growth mechanism of growth-step generation from the edges were discussed.
