The process disclosed enables aluminium oxide fibres containing up to about 40 wt % of Sio2 to be produced by reacting aluminium hydroxide or aluminium oxide hydrate with oxalic acid in an aqueous medium, optionally in the presence of an acid such as formic acid, to give aluminium oxalate, adding silicic acid and dry-spinning the solution obtained, optionally in the presence of spinning auxiliaries, and finally heating the aluminium oxalate fibres produced. |
