More Information
Summary:The present invention provides a method for the preparation of LiPF>6< (lithium hexafluoro phosphate) wherein equimolar quantities of pure dry AR lithium source such as Li>2<O or Li>23< or LiNO>3< is mixed with (very pure dry and AR samples) diammonium hydrogen phosphate in solid state. L'invention concerne un procédé de préparation de LiPF6 (lithium hexafluoro phosphate) dans lequel des quantités équimolaires d'une source lithium AR pur et sec, tel que Li2O ou Li2CO3 ou LiNO3, sont mélangées avec du phosphate diammoniacal d'hydrogène (échantillons secs très purs et AR).
