因产品是有腐蚀性的苛性钠，故称为苛化。碳酸钠(Na2CO3)和石灰乳[Ca(OH)2]制氢氧化钠的过程。
苛化剂 causticizer ; causticizing agent
苛化作用 [化学] causticization
苛化工段 liquor room ; causticization plant ; caustic room ; causticizing depatrment
辅助苛化 recausricizing
辅助苛化器 recausticizer ; auxiliary air causticizer

苛化时随碳酸氢钠初始浓度增大，平衡苛化率下降。
The equilibrium conversion decreases as the initial concentration of bicarbonate increases.
苛化需要45%以上的石灰，需要连续搅拌1到2小时使之全部溶解。
Up to 45% of lime is required, and the whole solution subsequently continuously agitated from 1 to 2 hours.
采用水浸-氧化锌苛化-碳酸化-萃取流程从未氧化的碳还原熔炼渣中提取钼和再生碱。
Using the process:water leaching, zinc oxide, causticize, carbonate, solvent extract, stripping to recycle molybdenum and to regenerate alkali.
