Talk:Hafnium tetrachloride

The article states that hafnium and chlorine react above 317 &deg;C: as the reaction has a high negative entropy change, it will be disfavored by high temperatures. Indeed, the reverse of the reaction is used for refining hafnium! The production section could do with double-checking and referencing. (but thanks, the article is coming on great!)
