Abstract
The behavior of frontally burning heterogeneous systems containing boron, aluminum, gallium, indium, yttrium, lanthanum, and ytterbium is studied by a potentiometric method. These systems are used for self-propagating high-temperature synthesis of some oxide materials. The peak values of the electromotive force of combustion arising between the combustion wave front and the synthesis products in systems with participation of triple-charged ions of these chemical elements are found to be directly proportional to the ionic potential of the chemical element and reach 150–400 mV. The use of two heteropolarly reacting systems as elements of the electromotive force of combustion in one array assembly allows the difference in potentials to be increased to 2.3 V.
