摘要：
The thermal decomposition of NPK fertilizers was studied by thermal analysis under dynamic and quasi-isothermal-quasi-isobaric conditions in open and labyrinth crucibles. It was found that under quasi-equilibrium conditions, the thermal analysis reveals mainly decomposition processes. The thermal stability of NPK fertilizers is characterized by the temperature of beginning of the spontaneous exothermic decomposition, at 180-190-degrees.
