The effect of the gaseous medium on the course of physico-chemical processes in semi-conducting oxides at high temperatures

Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    An investigation has been made of the effect of oxygen pressure on the kinetics of the reactions: ZnO+Al2O3= =ZnAl2O3 and MgO + Cr2O3=MgCr2O3.

  2. 2.

    Experimental confirmation has been produced for the general nature of the effect of the gaseous medium on the course of certain physico-chemical processes; for zinc oxide by comparing the reactivity, the catalytic activity and the electrical conductivity; for chromic oxide by comparing the reactivity and electrical conductivity; and for titanium dioxide by comparing the overall recrystallization the sintering and the electrical conductivitiy.

  3. 3.

    The kinetics of the physico-chemical processes considered are based upon deviations of the composition of semi-conducting oxides from the stoichiometric composition, as a result of the dissociation of the oxides or the adsorption of oxygen by them.
