In this paper,primary aluminum production and consumption status in the global and domestic are introduced,and the guarantee degree of bauxite resources and existing problems in China are analyzed.

As a main producer and net exporter of primary aluminum and aluminum products,China is now heading for a powerful aluminum producer in the world.

Effect of atmosphere on synthesis of titanium nitride in aluminothermic reduction process;

Using metal Al and TiO2 powders as starting materials TiN/Al2O3 composite ceramics were prepared by aluminothermic reduction of TiO2 in coke bed and a flowing nitrogen stream.

The result of thermodynamic calculation shows that the reduced products of V_2O_5 carbothermic reduction is the carbide of vanadium,the system of silicothermic reduction should add CaO,aluminothermic reduction can reach a reduc- tion rate of 99%,the reduction ability of Al is more effective than that of C and Si.

Finally,the significance of aluminium clusters research is given.

The reasons which improving the quality of aluminium metal and corresponding improvements were discussed on 70 kA HSS aluminium electrolytic cell with purified returns being main feed in Baotou Aluminium Co.

Dissipation of primary aluminium ingot is mainly affected by melting casting and compositive finished product rate when aluminium alloy is being processed.
