Green Synthesis of Manganese–cobalt–tungsten

2021-11-19  The manganese–cobalt–tungsten oxide composite (MCW) is synthesized by ball milling. First, 171.5 g of ball milling medium is put into the ball mill tank. Then, according to the designed proportion, a certain amount of MnO, CoO, and WO 3 were weighed and put into the ball mill tank, and the total quality is controlled at 3.5 g.
