Crystallization of potassium nitrate
WebThis method can obtain higher purity potassium nitrate compared to the recrystallization method, resulting in a purity of over 99.5% for potassium nitrate products. The obtained potassium nitrate products can be used in industries such as manufacturing gunpowder, metal welding aids, synthetic ammonia catalysts, glass products, ceramics, etc. WebSep 1, 2024 · Then evaporation and cooling crystallization are appended to separate the sodium nitrate and potassium nitrate from the potassium-enriched solution. Afterwards, the mother liquor was completely recycled, and ten cycle experiments were carried out to determine that the purity of potassium nitrate, which exceeded 99%.
