... ––––––––– ? 2.3 At 1 atmosphere, iron melts at 1536°C and boils at 2860°C. When it solidifies (a phase change), it does so in the b.c.c. crystal structure and is called δ -iron. On cooling further it undergoes ... f.c.c. crystal structure, and is then called γ -iron. The second is at 914°C when it changes back to the b.c.c. crystal structure, and is called α -iron. Teaching yourself...

... the oxides. One product of the oxygen blowing of molten iron is iron ‘fume’, which consists of iron oxide particles, Fe 2 O 3 . The rate of iron fuming has been studied in the laboratory, and found ... wider as the copper /iron ratio increases. In the iron sulphur binary system there is no miscibility gap at the temperature of copper conversion, but the liquid in contact with solid...
