制备

1.向2%～3%硝酸银溶液中加入过量的高锰酸钾，然后添加氢氧化钾。将过氧化银沉淀在砂芯漏斗中抽滤，用冰水洗涤直至洗涤水中颜色消失，并在40～50℃时干燥2h，这样制得的过氧化银中大约含有40%的氧化银。

2.在不断地搅拌下将72克粒状的氢氧化钠(1.8摩尔)分批地加入约85℃的1升水中。将75克(0.28摩尔)过二硫酸钾的浆状水液加到这个热碱溶液中，随后加入溶解在最少量水中的51克(0.30摩尔)硝酸银。将混合物的温度升高至90℃，并继续搅拌约15分钟。
将黑色的氧化银(1)沉淀在大的布氏漏斗上过滤，并用以氢氧化钠微微碱化的水洗涤沉淀以除去硫酸银。将产品风干。产量为35克(94%)。
