ABSTRACT:
A liquid composition comprising a solution of a water-soluble metal compound convertible to metal oxide and a smaller amount of a hydrolytically stable water-soluble organic silicone which may be used to prepare binders, coatings and shaped bodies, especially fibres, of intimate mixtures of metal oxide and silica. Preferred silicones are polysiloxane, polyoxyalkylene copolymers and preferred metal compounds are salts of aluminium and zirconium. Phase-stabilized alumina, especially in the form of fibres, is a particularly important embodiment; transitional alumina can be stabilized up to 1400.degree. C without the appearance of separate phases of mullite and crystalline silica.
