Аннотация

На основе построенной математической модели в макроскопическом приближении проведено теоретическое исследование твердофазного механохимического синтеза в бинарной порошковой смеси при ее механической обработке в механоактиваторе (энергонапряженном смесителе). Получены аналитические соотношения для параметров, определяющих процесс. С использованием найденных формул предложен способ нахождения эффективной кинетической константы, характеризующей степень гомогенизации порошковой смеси (метод обратной задачи).
