CAS 13499-05-3: Tetracloruro di afnio
Descrizione:
Tetracloruro di afnio (HfCl4) è un composto inorganico caratterizzato dalla sua forma solida cristallina bianca a temperatura ambiente. È un composto covalente, che presenta una geometria molecolare tetraedrica. Tetracloruro di afnio è altamente solubile in solventi organici come benzene e toluene, ma ha una solubilità limitata in acqua. È noto per la sua natura igroscopica, assorbendo facilmente l'umidità dall'aria, il che può portare a idrolisi e alla formazione di ossicloruro di hafnio. HfCl4 è utilizzato principalmente nella produzione di metallo di hafnio e come precursore nei processi di deposizione di vapore chimico per film sottili di ossido di hafnio, che sono importanti nelle applicazioni dei semiconduttori. Il composto ha un punto di fusione relativamente alto e può essere sublimato sotto vuoto. A causa della sua reattività, in particolare con acqua e basi, la manipolazione di HfCl4 richiede cautela, poiché può rilasciare acido cloridrico al contatto con l'umidità. In generale, Tetracloruro di afnio gioca un ruolo significativo nella scienza dei materiali e nei processi di produzione avanzata.
