'''三碱式硫酸铅'''（{{lang|en|Tribasic lead sulfate}}），别名'''三[[盐基]]硫酸铅'''，化学式3PbO·PbSO<sub>4</sub>·H<sub>2</sub>O。它在欧盟经济区的生产量或进口量超10万吨/年。<ref name=ECHA>{{cite web|url=https://echa.europa.eu/substance-information/-/substanceinfo/100.032.152|title=Tetralead trioxide sulphate|publisher=ECHA|accessdate=2025-03-11}}</ref>它可用于聚合物或涂料产品的生产。<ref name=ECHA />

==性质==
三碱式硫酸铅为白色至微黄色粉末。820°C为熔点。溶于[[水]]、[[硝酸]]、热浓[[盐酸]]、[[乙酸铵]]、[[乙酸钠]]溶液，微溶于[[乙酸]]、不溶于[[乙醇]]。为有毒化学物品。

==制备==
[[氧化铅]]的水浆液与少量[[乙酸]]混合，并在搅拌下加入一定比例的[[硫酸]]进行反应，反应后料浆经干燥、粉碎，制得三碱式硫酸铅。
