采用DSC和激冷实验对Al-TiO2的SHS反应过程进行了详细的研究。结果表明，Al还原TiO2的过程为：液态Al在TiO2颗粒表面铺展并与Al反应，从而在TiO2颗粒周围形成中间产物层TiO2－x，此后还原过程不断通过氧在中间产物层TiO2－x中的扩散而进行。
The SHS reaction process of Al-TiO2 system was studied by means of DSC and quenching experiment. The results show that the intermediate compounds of TiO2－x is formed when molten Al spreads on the surface of TiO2 particles.And the key factor of the reduction reaction in Al-TiO2 system is the oxygen diffusion through TiO2－x layers.
