用化学反应法在水溶液中用次亚磷酸钠还原氯化钴制得了纯净的钴－磷非晶合金超细微粒．通过一系列的实验，研究了反应条件（如初始ｐＨ值、反应时间以及添加剂等）对反应产物的影响，并且对产物进行了表征．在反应的初始ｐＨ值为１１和１２时，制得了平均粒度为１５０ｎｍ的粒度相对均匀的钴－磷非晶合金超细微粒
Using chemical reaction method in aqueous solution with sodium hypophosphite reduction of cobalt chloride to obtain a pure cobalt-phosphorus amorphous alloy ultrafine particles. Through a series of experiments, the effects of reaction conditions (such as initial pH value, reaction time and additives) on the reaction products were studied and the products were characterized. At the initial reaction pH of 11 and 12, cobalt-phosphorus amorphous alloy ultrafine particles having a relatively uniform particle size of 150 nm were obtained
