Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the ...

A new method for reducing iron-ore without greenhouse effect gas exhaust was developed to prevent the global warming. The reduction of α-Fe 2 O 3 (hematite) by ball-milling with hydrogen gas flow was studied by XRD, SEM, TEM and Moess spectroscopy. Iron oxide (α-Fe 2 O 3) powder was charged into a container for ball-milling with stainless steel balls.
Rotation of the trommel, agitation and dropping of the contents, helped by the addition of larger rocks which made the trommel a small-scale "ball mill" (used for crushing ore), sent most of the contents through a screen of one-quarter inch mesh. Then came the crowning and highly original method of …
