Notes:
The combustion process of Mg-TiO2 system was preliminarily investigated from threeaspects of thermodynamics, reaction kinetics and the technological parameters. The result indicatesthat the adiabatic temperature of Mg-TiO2 system is between 2060K and 2140K because the majorexistent modalities of TiO2 is the rutile and anatase, this meets the empirical criterion that the SHSreaction will be self-sustaining; The solid-solid reaction occurs at about 767K; Ti powders can beproduced only when the ratio between Mg and TiO2 arrives at 2.9:1; The higher the vacuum, themore complete the reaction; The combustion temperature arrives at its peak when the pressure ofgreen compact arrives at 250MPa; the velocity of the combustion wave increases with theaugmentation of the pressure of green compact. So the proper control of the technologicalparameters can change the reaction temperature, reaction rate and the components of reactionproducts
