ABSTRACT:
In a process for producing a high density article of titanium diboride, a titanium diboride powder mixture is formed into a compact shape, and then sintered according to a two step sintering process with one step being at a low furnace pressure to close the surface porosity of the compact and the second sintering step being at a higher over pressure to form a high density article.
