Abstract
The K2TiF6 salt required for the production of Al–Ti and Al–Ti–B master alloys was synthesised in the laboratory and the dissociation behaviour of K2TiF6 and KBF4 salts at different temperatures was studied. An investigation was carried out of the mode of reaction of the salts with aluminium. The salts were found to react with aluminium directly without undergoing dissociation. The K2TiF6 salt reacts with aluminium only when the aluminium is molten, while the KBF4 salt reacts with solid aluminium. In the presence of KBF4, the reaction between K2TiF6 and aluminium takes place below the melting point of aluminium.MST/3233
