Mass transfer of zinc-containing compounds during filtration combustion in the counterflow regime: 3. Mass transfer at a low content of the zinc-containing component in the initial stock

The regularities of filtration combustion and of the mass transfer of zinc-containing products from model stock compositions with a low content of the zinc-containing component were experimentally studied over a range of governing parameters. The parameters of the combustion of stock samples, degree of extraction of zinc-containing products into sublimate from the condensed sample, and chemical form of the zinc-containing compounds released were determined. The results obtained were discussed.
