质软而轻。化学性质活泼,在空气中易氧化。遇水能引起剧烈的反应,使水分解而放出氢气和热量,同时引起燃烧,呈蓝色火焰。也可与乙醇和酸类起剧烈反应。与饱和的脂肪烃或芳香烃无反应。溶于多种金属形成合金。不溶于烃类,溶于液氨、乙二胺和苯胺。溶于乙醇、丙酮、甲醇、甘油和液氯,微溶于乙醚,易溶于水。检定氮、硫、磷、钾和钠等。无机及有机合成。还原剂。热传递介质。 作制备碘化物和染料的原料,医药上作甲状腺肿防治剂、眼玻璃体浑浊的吸收剂、祛痰剂和利尿剂。观光材料工业用作感光乳化剂、彩色照片媒染剂。还用作食品添加剂、助熔剂和石版印刷,也用作分析试剂、色层分析和点滴分析。 Potassium can be used in the synthesis of potassium containing solid-state chalcogenides with promising thermoelectric properties. It may also be used in the dehalogenation of 1,3-di-tert-butyl-2,2-dichloro-1,3-diaza-2-sila-4-cyclopentene to form 1,3-di-tert-butyl-2,3-dihydro-1H-1,3,2-diazasilol-2-ylidene.
