ABSTRACT:
A densified silicon nitride body can be formed using a lanthana-based sintering aid. The composition may exhibit properties that provide a material useful in a variety of applications that can benefit from improved wear characteristics. The composition may be densified by sintering and hot isostatic pressing.
