A method for producing densified aluminum nitride articles having enhanced thermal conductivity is disclosed. The method comprises the steps of forming a powder compact comprising aluminum nitride alone or in combination with other ceramic compounds, adding a densification aid to the compact, and at least partially densifying the compact via sintering or hot pressing to provide a semi-dense article. This semi-dense article is thereafter exposed to an atmosphere containing vapor phase carbon for a period of time sufficient to allow the vapor phase carbon to reduce the level of oxygen contained within the article. The article thus produced is a dense aluminum nitride article having a high thermal conductivity. |
