ball milling in hajra choudhary 2017

The preparation process consists of oxidation hydrogen reduction and carbonization the results show that the performance of the wcco composite powder mainly depends on the mild hydrogen reduction and carbon layer when the milling time is 40 h the oxide phase of wo 3 transforms into wo 272 in a mild reduction process
