Potassium fulminate is the potassium salt of the fulminate ion. Its only use, aside from chemical demonstrations, is in the percussion caps for some early rifles. Usually prepared by reacting a potassium amalgam with mercury fulminate,[1] it is much less sensitive due to the ionic bond between potassium and carbon, unlike the weaker covalent bond between mercury and carbon.
