Beschreibung
Zusammenfassung:	FIELD: inorganic compounds technologies. ^ SUBSTANCE: invention relates to preparation of ammonium nitrate with structure resistant to temperature changes and provides an ammonium nitrate phase stabilization method involving addition of organic stabilizer selected from group of nitrogen-containing heterocycles with imine and carbonyl groups, which stabilizer is added to ammonium nitrate in amounts ranging from 4 to 34 wt %. Thus obtained combination is mixed and resulting mixture is ground into powder or heated to 130-160°C at stirring and cooled. Ammonium nitrate obtained by this method is resistant to repetitive changes in temperature within a range from -50 to +100°C, which allows it to be utilized, in particular, in gas-generation compositions for inflators in automobile safety bags. ^ EFFECT: enhanced temperature resistance of ammonium nitrate phase. ^ 7 cl, 16 ex
