雷酸银（AgCNO）是雷酸的银盐，极具爆炸性。

雷酸银是一种起爆药，由于它对热、压力和电极度敏感，因此它几乎没有实用价值。随着雷酸银的聚集，它变得越来越敏感，即使量很少；一堆水下的雷酸银，不大于一角硬币、没有几毫克重，下落羽毛的轻触、一滴水的影响、或一次小的静电放电都能够将其引爆。不可能聚集起较大量雷酸银，因为其自身重量将会使其爆炸。

雷酸银首先由爱德华·查尔斯·霍华德于1800年在他的研究项目中制备，当时他在制备种类繁多的雷酸盐。自从发现以来，它一直被用于制作无害的、能发出响声的儿童玩具。

Silver fulminate (AgCNO) is the highly explosive silver salt of fulminic acid.

Silver fulminate is a primary explosive but has limited use as such due to its extreme sensitivity to impact, heat, pressure and electricity. The compound becomes progressively sensitive as it is aggregated, even in small amounts; the touch of a falling feather, the impact of a single water droplet or a small static discharge are all capable of explosively detonating an unconfined pile of silver fulminate no larger than a dime and no heavier than a few milligrams. Aggregation of larger quantities is impossible due to the compound's tendency to self-detonate under its own weight.
