Sic Powder Ball Milling From Ethiopia

Sic Powder Ball Milling From Ethiopia

Sep 01, 2010 Ti 3 SiC 2 powder was milled by high-energy ball milling under argon atmosphere and subsequently thermally annealed. The microstructure evolution of Ti 3 SiC 2 after milling was investigated. It was found that 200 nm particle size Ti 3 SiC 2 powder could be achieved by 9 h milling whereas a longer milling time would induce Ti 3 SiC 2 decomposition. After 18. h milling, the particle
