Procedure

In accordance with the present invention, when equimolar amounts of tetraborates and one of the following inorganic ammonium salts: ammoniumsulfate, ammoniumsulfite or diammoniumhydrophosphate are heated in a water solution and about 60% of the theoretical ammonia content is distilled off, new and stable flame retardant compositions: ammoniumpentaborate and the corresponding alkali salt sulfate, sulfite or hydrophosphate are obtained. The same compositions are obtained after the suspension of a tetraborate in two equivalent amounts of ammonia is treated with one equivalent amount of concentrated sulfuric acid, sulfurdioxide or phosphoric acid. In case of milling, dry heating, suspending or dissolving tetraborates with the above ammonium salts, a partial formation of ammoniumpentaborate and corresponding inorganic salts are obtained with concomitant evolution of ammonia gas.
