Abstract

1296564 Cryolite UGINE KUHLMANN 3 Aug 1970 [20 Jan 1970] 37340/70 Addition to 900790 Heading C1A Na 3 AlF 6 is obtained by the process of parent Specification in which the solution is replenished by addition of Na 3 AlF 6 produced by reaction of H 3 AlF 6 and NaCl. This is preferably performed by adding aqueous solutions containing the stoichiometric amounts necessary for the reaction. The H 3 AlF 6 may be produced in situ by reacting HF with Al(OH) 3 and possibly H 2 SiF 6 .
