Silver cyanate vs silver fulminate a highly explosive comparison


Silver cyanate is a chemical compound; it is the cyanate salt of silver.

It can be prepared by the reaction of potassium cyanate or urea with silver nitrate.

A g N O 3 + K O C N ⟶ A g O C N ↓ +   K N O 3 A g N O 3 + H 2 N - C ( O ) - N H 2 ⟶ A g O C N ↓ +   N H 4 N O 3

Silver cyanate is a beige to gray powder. It crystallises in the monoclinic crystal system in space group P21/m with parameters a = 547.3 pm, b = 637.2 pm, c = 341.6 pm und β = 91°.

With nitric acid, silver cyanate reacts to form carbon dioxide and ammonium nitrate.
