Production and behaviour of the amalgams of the IV a-, V a-, and VI a group metals


The usual methods for the production of amalgams—dissolving of metals in mercury, or electrolytic deposition on mercury—are not suitable for the preparation of amalgams of transition metals. However amalgams of the transitions elements can be prepared by reduction of their dry halides with sodium amalgam. These amalgams are unstable against aqueous solutions under oxidising conditions and decompose by dewetting of the suspended metal particles. The stability can be improved by addition of components, e.g. oxalic acid or HF to the solution, which prevent the formation of oxide layers on the dewetted metal particles. By using such solutions in processing the reaction products of the halides with sodium amalgam the amalgams of the transition elements can be obtained without decomposition.
