Calcium Metaplumbate, CaPbO3
Calcium Metaplumbate, CaPbO3, is formed when the orthoplumbate is digested with water and sodium peroxide. It is a white, crystalline powder, which, according to analysis, contains four molecules of water. The same salt is formed, mixed with calcium hydroxide, when Ca2PbO4.4H2O is heated to 240°-250° C. so as to lose three-quarters of its water. The orthoplumbate is regenerated when the meta-salt is heated with lime to 500° C. Silver, zinc, and cupric metaplumbates have been prepared from the calcium salt.
