Boric metal
WebJan 30, 2024 · Alkali metal hydroxides LiOH, NaOH, KOH, CsOH are soluble, and their solutions are basic. Hydroxides of alkali earth metals are much less soluble. For example, quicklime ( CaO) reacts with water to give slaked lime, which is slightly soluble. (1) CaO + H 2 O ⇌ Ca ( OH) 2 quicklime slaked lime (slightly soluble) Webborated water was dripped onto a hot metal surface, similar to the ANO-1 experience. The report concluded that aggressive boric acid corrosion of locally cooled low-alloy steel parts can occur when the plant is at operating temperatures. The dripping borated water solution concentrates as the water boils off.
