Nella Parte 1 abbiamo parlato della formazione del tungsteno nell’Universo e del perché abbia due nomi, per poi approfondire le proprietà tecnologiche del suo composto più utilizzato, il carburo di formula WC. In questa seconda parte viene sottolineata l’importanza , per i Paesi manifatturieri, del carburo di tungsteno, che rappresenta circa il 60% dellʼimpiego globale dellʼelemento. Infine, viene presentato, in linea con gli obiettivi dellʼAgenda 2030 dell'ONU, un metodo alternativo, energeticamente più efficiente e a minore impatto ambientale, per la produzione del WC dal minerale.
In the previous Part 1 we discussed the formation in the Universe of the element with Z = 74, where its two names (tungsten and wolfram) come from, and the technological importance of tungsten monocarbide, WC. In Part 2 we show that tungsten is of utmost strategic importance for manufacturing countries, and WC represents more than half of the global use of the element. Finally, an alternative process with lower environmental impact for the direct synthesis of WC powders from the minerals is proposed.
