摘要
本文报道了采用溶液降温法在甲醇溶液中加入1-5%的乙醇胺添加剂,快速高效地生长出(001)方向长度大于185mm 的透明尿素长棒籽晶,满足了用 Z 向限制方法生长大尺寸尿素晶体长籽晶的需要。
Rapid growth of urea seed crystals above 185mm in the(001)direction was successfully carried out by the aqueous solution cooling methodfrom methanol solution with additives of 1-5% ethanolamine.This can meetthe demand for long seed crystals for growing large sized urea crystals bythe Z-direction restricted growth method.
