WebMar 3, 2024 · Potassium nitrate has a molar mass of 101.10 grams per mole. It has a boiling point of 400 °C (752 °F), a melting point of 334 °C (633 °F), and a density of 2.11 grams per cubic centimetre at 25 °C (70 °F). It is soluble in water at 38.3 grams per 100 millilitres at 25 °C but is only slightly soluble in most alcohols. It is insoluble in ethanol. WebIn some cases like the eutectic composition of Na–K with 78% potassium, the melting temperature is as low as −11°C [17,27], facilitating its use as heat transfer fluid in solar thermal power plants without making use of heat tracing systems that usually increment costs of maintenance and are parasitic.
