In contact with air, pure molten potassium nitrate is stable up to about 530 deg C. Above 750 deg C, the nitrite product decomposes with the formation of nitrogen oxides.
Heat of fusion: 2840 cal/g mole= 28.1 cal/g
Transition point: 129 deg C from rhombic to trigonal form
Transparent, slightly hygroscopic
Dissolves in water with a lowering of the temp
Oxidizing material
