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.
Claims9
A process for producing a sintered AlN ceramic body comprising:
- mixing a hydrocarbon solvent, an organometallic compound selected from the group consisting of metal alkoxides and metal alkoxycarboxylates, and AlN powder to produce a slurry having an amount of said organometallic compound ranging from about 0.1-12% by weight with respect to the dry weight of said AlN powder;
- removing said solvent from said slurry to form a mixture of organometallic compound and AlN;
- forming said mixture into a shape;
- and
- sintering said shape in a non-oxidizing atmosphere to obtain densification.
