Abstract
During the manufacture of milk of lime by the suspension of lime hydrate which has a large specific surface and was manufactured with the use of organic solvents and/or organic additives, a stable foam forms which can cause problems in the equipment. This foaming can be prevented during the suspension of the modified lime hydrate in water by the presence of finely-powdered activated cokes.
