The process of the present invention for preparing granules of alumina includes pretreating an alumina powder by admixing with cold water in a mixer at a temperature below room temperature, e. g. , such as below about 20. degree. C. , to form a pretreated alumina having a pore volume saturated with water and further having a surface area of gel structure, and agglomerating the pretreated alumina in a fluidized bed to form granules. The process is particularly suited to producing activated alumina in macroporous granules. The process in one aspect further includes a cold hopper for cooling alumina powder prior to the pretreating step.

A composite jet engine compressor ring is made by casting a tape reinforced with ceramic fibers, winding the cast tape around a mandrel to form an unconsolidated ring, heating the ring to drive off binder, and pressing at a high temperature to form a unitary composite ring. Compression of the ring in an axial direction during hot pressing results in a desired axial spacing between adjacent fibers. The tape is preferably cast from a mixture of titanium base metal particles and a polyisobutylene binder dissolved in an organic solvent.

Aluminous material is chlorinated in the presence of a reducing agent at pressures greater than three atmospheres. A greater than linear increase in reaction rate obtained at superatmospheric pressures is a feature of the chlorination reaction which is employed to increase aluminum chloride production rate. Choice of pressure used is governed more by mechanical limitations than by an upper limit inherent to the chemical reaction.

The process of the present invention for preparing granules of alumina includes pretreating an alumina powder by admixing with cold water in a mixer at a temperature below room temperature, e. g. , such as below about 20. degree. C. , to form a pretreated alumina having a pore volume saturated with water and further having a surface area of gel structure, and agglomerating the pretreated alumina in a fluidized bed to form granules sized in the range of about 1-3 mm. The process is particularly suited to producing activated alumina in macroporous granules. The process in one aspect further includes a cold hopper for cooling alumina powder prior to the pretreating step.

A fiber reinforced composite tape is made by casting a mixture comprising high temperature metal or intermetallic particles, substantially continuous ceramic fibers and a polymeric binder. The particles are preferably titanium alloy or titanium aluminide particles having a top size of greater than about 50 microns and the binder is preferably a polyisobutylene. The cast composite tape is combined with other tapes, heated in a vacuum to remove the binder and pressed at an elevated temperature and pressure to form a composite structure suitable for high temperature applications.
