Answer Finely powdered bauxite (Al2 O3 )is heated with coke and N2 to 2000 K. Alumina forms aluminium nitride and silica is reduced to Si which is volatile. The hydrolysis of aluminium nitride gives aluminium hydroxide which on heating gives pure alumina. Al2 O3 ⋅2H2 O+N2 +3C2000K 2AlN+3CO↑+2H2 O SiO2 +2C→Si↑+2CO↑ AlN+3H2 O→Al(OH)3 ↓+NH3
