The invention relates to a method for producing ammonia. Using SiO2 and/or Al2O3 or SiO2- and/or AI2O3-containing material, silicon nitride and/or aluminum nitride is obtained, which is reacted with water in the presence of a basic alkali and/or earth alkali metal compound at an elevated temperature to form ammonia and alkali and/or earth alkali metal silicates. The method enables particularly effective utilization of natural resources.
