Electrochemical Reduction of Tungsten Compounds to Produce Tungsten Powder
Metallurgical and Materials Transactions B: Process Metallurgy and Materials Processing Science, 2010 The production of tungsten by direct current reduction has been investigated. Experimental studies involved the electrochemical reduction of the solid tungsten compounds tungsten trioxide (WO3) and calcium tungstate (CaWO4) in the form of an assembled cathode of porous pellets attached to a current collector.

Tungsten Biscorroles: New Chiral Sandwich Compounds
Chemistry - A European Journal, 2016 AbstractThe oxidative metalation method, involving the interaction of free‐base meso‐triarylcorroles and W(CO)6 in refluxing decalin, led to a set of three tungsten(VI) biscorroles, the first homoleptic sandwich compounds involving corroles. Single‐crystal X‐ray structures of two of the complexes revealed square‐antiprismatic coordination and strongly ...
