摘要 具有通式 M3B7O13X（其中 M 是二价阳离子，通常是 Mg、Mn、Ni、Cu Fe 等，X 是 Cl−、Br− 或 I−）的方硼石单晶最近因其在热释电探测器中的潜在应用而引起人们的兴趣，特别是用作热释电摄像机目标。下面的讨论描述了如何使用 NiBr 和 FeI 硼酸盐生长过程中存在的气相热力学分析来开发限制自发成核密度并允许晶体在先前引入的晶种上生长的技术。
Abstract Boracite single crystals with the general formula M3B7O13X (where M is a divalent cation, typically Mg, Mn, Ni, Cu Fe etc., and X is Cl−, Br− or I−) have recently excited interest for their potential applications to pyroelectric detectors, particularly for use as pyroelectric vidicon targets. The following discussion describes the way in which a thermodynamic analysis of the gaseous phases present during the growth of NiBr and FeI boracites has been used to develop a technique for the restriction of the density of spontaneous nucleation and to permit the growth of crystals onto previously-introduced seeds.
