For example, aluminium will reduce iron ( III ) oxide to iron, becoming aluminium oxide in the process:
42.
These use grains of aluminium oxide or silicon carbide, bonded to a non-woven web of nylon fibres.
43.
Borazon replaced aluminium oxide for grinding hardened steels owing to its superior abrasive properties, comparable to that of diamond.
44.
Aluminium oxide is very durable and extremely hard; it occurs naturally as corundum, and finds applications in sandpaper.
45.
Traditional ceramic raw materials include clay minerals such as kaolinite, more recent materials include aluminium oxide ( alumina ).
46.
The dross is first crushed then separated into aluminium metal rich particles and aluminium oxide rich particles based on density.
47.
This aluminium oxide layer serves as a protective barrier to the underlying aluminium itself and preventing chemical reactions with the metal.
48.
However, it is possible to mechanically recharge the battery with new aluminium anodes made from recycling the hydrated aluminium oxide.
49.
The sintering process involves mixing beryl with sodium fluorosilicate and soda at to form sodium fluoroberyllate, aluminium oxide and silicon dioxide.
50.
Cobalt blue, a pigment of cobalt oxide-aluminium oxide, was a favourite of Auguste Renoir and Vincent van Gogh.
