General description

Anhydrous form of copper sulfate occurs as mineral hydrocyanite. It exhibits a rhombic crystalline morphology. It decomposes to its oxide at temperatures above 600oC. Hydrate of CuSO4 is prepared by the addition of dilute sulfuric acid on copper (II) oxide or copper (II) carbonate, blue triclinic crystals of pentahydrate are formed upon crystallization. In industrial preparation of CuSO4, a hot mixture of dilute sulfuric acid and scrap copper is exposed to air flow.

Application

This anhydrous salt may be used in the electroplating and mining industries and to preserve wood in combination chromium and arsenic.

At elevated temperatures, bimetallic nanomaterials change their morphologies because of the interdiffusion of atomic species, which also alters their properties. The Kirkendall effect (KE) is a well-known phenomenon associated with such interdiffusion. Here, we show how KE can manifest in
