Abstract
Disclosed is a method of forming an aluminum nitride article. The method includes the steps of adding platinum to a composition including a binder, aluminum nitride particles and a sintering aid; forming the composition into an article; placing the article in a substantially non-carbonaceous container; and sintering the article in a reducing atmosphere to cause removal of the binder and densification of the aluminum nitride article, wherein the platinum catalyzes the removal of the binder.
