"Effects of Ball Milling and Sintering on Alumina and ...

Alumina has a wide variety of appliions, but the processing of alumina based materials can be costly. Mechanically milling alumina has been shown to enhance the sintering properties while decreasing the sintering temperature. Additions of boron have also proven to increase sintering properties of alumina. These two processes, mechanical milling and boron additions, will be combined to test ...
