Potassium Nitrate — Phase Transitions

Potassium nitrate (KNO3) is used for the synthesis of gunpowder (sulphur, char and KNO3). It is also used in food preservation (E252) and as an important potassium- and nitrogencontaining fertilizer. The measurement was carried out in scanning mode with a constant power input of 200 mW. Two endothermal effects at 129°C (peak area of -45 J/g) and at 334°C (-87 J/g) are related to phase transitions. (measurement with MMC 274 Nexus®)
