Abstract:
1. A silicone rubber or paper comprising an ultrafine mixed-crystal oxide characterized in that the ultrafine mixed-crystal oxide comprises primary particles in a mixed crystal state with a BET specific surface area of about 10 to about 200 m 2 /g, and is produced by a process comprising the step of subjecting a halogenated metal to high temperature oxidation with an oxidizing gas to produce a metal oxide by a vapor phase production method, wherein said halogenated metal is in the form of a material gas containing a mixed halogenated metal gas comprising at least two compounds each having a different metal element selected from the group consisting of chlorides, bromides, and iodides of titanium, silicon, and aluminum, and said mixed halogenated metal gas and said oxidizing gas are supplied into a reaction tube at a flow velocity of 10 m/sec or more to react after each is independently preheated to about 500° C. or more prior to a reaction.
