Uses and applications

What the substance is used for, by industry and function

Used as a component in triple-based propellants, impact-insensitive military ammunition and as a gas generator in automotive airbag applications, used in anticorrosive phosphate coatings.

High explosives, especially flashless propellant powder (with nitrocellulose), chemical intermediate.

Industrial uses: Surface modifier.

How it is made

Prepared by the action of concentrated H2SO4 on guanidine nitrate.

Prepared by the nitration of guanidine sulfate with fuming HNO3. Is converted into the alpha-form by dissolving in concentrated H2SO4 and pouring into ice water. (beta-form)

(beta) Nitration of a mixture of guanidine sulfate and ammonium sulfate that results from the hydrolysis of dicyanadiamide by sulfuric acid.
