Установлено образование в процессе совместного отжига оксидов гетерогенного материала с преобладанием фазы СоWО4, а также существенное возрастание чувствительности смешанной композиции к 2 ppm диоксида азота по сравнению с исходным WO3.</p></abstract><trans-abstract xml:lang="en"><p>Tungsten oxide WO3, cobalt oxide Co3O4 and their compositions prepared by the sol-gel method, have been characterized by X-ray diffraction (XRD), IR-spectroscopy, scanning electron microscopy (SEM), thermogravimetric and differential thermal analysis (TG-DTA). The formation of heterogeneous material consisting mainly of CoWO4 in the process of joint annealing of oxides has been established. It has been observed that the mixed composition is much more sensitive to nitrogen dioxide (2 ppm) than the starting material, WO3.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pullar R.
