Platinum fulminate is a primary explosive which is a fulminate salt of platinum discovered by Edmund Davy.^[2][3][4][5]

Synthesis

Platinum is mixed with nitric acid, making platinum sulfate with the formula Pt(SO₄). The sulfate solution is then precipitated out with ammonia, and then placed in a flask with potassium hydroxide and heated to a boil. The remaining precipitate is then filtered out, washed, and dried to yield Platinum fulminate.^[6]
