一种方法是通过氧氯化铜与在稳定剂以及分离和洗出的反应产物的存在碱金属或碱土金属氢氧化物的含水悬浮液为反应氢氧化铜的制备中所述。 为了获得氢氧化铜的改进的稳定性，并避免由氧化铜黑化，无机硅化合物加入到所述分子或形式中的羟基基团（SiOH基）在水性介质中。 合适地，使用细颗粒固体或水溶性或胶态溶解的硅酸。

A method is described for producing cupric hydroxide by reacting copper oxychloride in an aqueous suspension with alkali or alkaline earth metal hydroxide in the presence of stabilizing agents as well as separating and washing out the reaction product. In order to achieve an improved stability of the copper hydroxide and to avoid blackening by copper oxide, inorganic silicon compounds are added to the hydroxyl groups (SiOH) in the molecule or form in an aqueous medium. Suitably finely divided solid or water-soluble or colloidally dissolved silicas.
