1.将硫酸铵与氯酸钾溶于热水中进行反应：
硫酸铵用量可稍大于理论值。不断搅拌下将溶液蒸发至稠状，然后冷却，所得物用80%的乙醇处理，滤出硫酸钾沉淀，用乙醇洗涤。滤液与洗涤液一并蒸馏，出去乙醇后，在水浴上加热（小心氯酸铵能发生爆炸），再加入过量氢氧化钡的饱和溶液，制得氯酸钡。
当氨气不再放出（嗅不到氨味）及溶液显明显碱性，停止加热，然后将溶液蒸发近干，用5倍量的水溶解所得物通入二氧化碳以除去剩余氢氧化钡，过滤，滤液蒸发浓缩至刚出现结晶时冷却结晶，离心甩干。在30-50 ºC下干燥，即得结晶氯酸钡。
2.把122.6g KClO3和70g(NH4)2SO4置于瓷皿中，加350mL热水，一面不停搅拌，一面蒸发，直到生成稀薄糊状物。冷却后加4倍80%乙醇，使NH4ClO3与不溶的K2SO4分离。K2SO4残渣用乙醇洗涤几次。将溶液蒸馏，使乙醇与残余的固体物质分离。将残留的NH4ClO3置瓷皿中，在水浴上加Ba(OH)2·8H2O的热浓溶液。［至少用160g Ba(OH)2·8H2O溶于160mL热水］直到NH3味消失，最后溶液呈明显的碱性反应为止。将溶液蒸发至干，把残渣溶于5倍水中。把CO2通入溶液，使BaCO3完全沉淀，抽滤，并将滤液蒸发到结晶。
