It is used as a component in pyrotechnical compositions, in inustrial explosives, and in black power. 

Though the theoretical Isp of black powder is less than that of single-base, doublebase, and AP-based composite propellants, black power is useful for short-duration operation of simplified propulsive systems. The advantages of black power are low cost, very low aging effect, simple adjustment of propulsive forces by the adjustment of the quantity.

The rapid heating is one of the characteristics of microwave heating. But if the temperature rising is too fast, there are some low melting point eutectics to be produced in the process of decomposition meanwhile, it could produce some black power material.
