A process for producing a sintered AlN ceramic body by mixing an organic solution comprising a hydrocarbon solvent and an organometallic compound with AlN powder to produce a slurry, removing the solvent from the slurry to form a mixture of organometallic compound and AlN, forming the mixture into a shape, and heating the shape in a non-oxidizing atmosphere to sintering temperature to obtain densification.

Graphite composite articles comprising a graphite structure formed from a porous graphite material and an impregnant selected from the group consisting of glass precursors and ceramic precursors, filling the pores and coating the surface of the structure. The present invention also provides a process for the manufacture of graphite composites comprising the steps of infiltrating a porous graphite structure with a material selected from the group consisting of glass precursors and ceramic precursors and subsequently converting the precursor to a glass or a ceramic respectively.

Graphite composites and process for the manufacture thereof

A method for preparing substrates for VLS fiber producing reactions and a method for preparing SiC fibers by the VLS process. The first method includes the steps of forming an alcohol sol containing a fiber growth promoter material precursor, applying the sol to at least one surface of the substrate and drying the sol. More particularly, the steps can include forming a sol of colloidal hydrous metal oxide particles in a liquid, the metal oxide being a fiber growth promoter material precursor and the liquid being capable of dissolving a salt of the metal and of wetting the substrate surface as a sol, applying the sol to at least one surface of the substrate and drying the sol. The method for the production of SiC fibers includes the steps of applying to at least one surface of a non-metallic, high temperature resistant substrate a sol coating containing a SiC fiber growth promoter material precursor, drying the sol coating and contacting the substrate with silicon and carbon containing gases at a temperature of about 1300.degree. C. to about 1500.degree. C.

High surface area open microporous, partially crystalline, partially amorphous, solid ceramic materials containing silicon carbide with or without silica with or without carbon may be prepared by controlled pyrolysis of (RSiO.sub.1.5).sub.n gels in an inert atmosphere. The silica and carbon content, surface area, and pore size and distribution may be altered by optional subsequent processing steps to selectively remove carbon and/or silica.

Amorphous metal alloy powders may be synthesized by solid state reactions. Precursor components that include the elements of the amorphous alloy are chemically reduced to yield an intimate mixture. The resultant intimate mixture, as obtained or after heat-treating, exhibits amorphous characteristics. These powders are suitable for forming solid amorphous shapes.

Solid catalysts comprising a solid inorganic catalyst support material and polymeric transition metal complex are ideally suited for use as solid catalysts in various vapor phase heterogeneous continuous reactions.

Metal coordination polymers as hydroformylation and hydrogenation

A methane conversion process is provided for the production of olefins and hydrogen comprising contacting methane in the absence of oxygen and in the absence of water at a reaction temperature of at least 500.degree. C. with a catalyst comprising the mixed oxides of a first metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures thereof, a second metal selected from beryllium, magnesium, calcium, strontium, barium, and mixtures thereof, and optionally a promoter metal selected from copper, rhenium, tungsten, zirconium, rhodium, and mixtures thereof.
