Abstract
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.
