CN103305899A 一种水热法生长大尺寸砷酸钛氧钾体单晶的方法 无效 - 驳回

一种水热法生长大尺寸砷酸钛氧钾体单晶的方法
摘要：
本发明公开了一种水热法生长大尺寸砷酸钛氧钾体单晶的方法，它是在高压釜中，以氟离子浓度为0.5～4mol/L的氟化钾溶液作为矿化剂，使砷酸钛氧钾溶解并重结晶生长单晶体的方法。与现有技术相比，本发明所述方法仅以0.5～4mol/L的氟化钾溶液作为矿化剂，矿化剂体系的组成更简单，毒性更低，在减少环境污染的同时也降低对操作人员的危害性；生长条件也更温和；整个方法简单易操作，获得的体单晶完整无裂痕，且光学质量好，透过率可达70%以上。
摘要（英）：

The invention discloses a method for growing large-size kalium titanyl arsenate single crystals through a hydrothermal process, and particularly relates to a method for dissolving kalium titanyl arsenate and recrystallizing the solution to grow single crystals with a potassium fluoride solution having a fluorine ion concentration ranging from 0.5 to 4 mol/L as a mineralizer. Compared with the prior art, the method provided by the invention is characterized in that only 0.5-4 mol/L potassium fluoride solution is utilized as the mineralizer, so that the mineralizer system is simpler in constitution and lower in toxicity and harm on an operator is reduced while the environmental pollution is reduced, the growth conditions of the method also are mild, the whole method is simple and easy to operate, and the obtained single crystals are complete without cracks and good in optical quality; besides, the transmittance of the single crystals reaches 70% or higher.
