The Influence of the Grain Size of the Batch Materials on the Rate of Melting

JSGT_1929_V13_T057_T063

In work in a chemical laboratory it is a recognised rule that in order to speed up the chemical action between substances which are to react they must be brought into contact as intimately as possible. When the materials are solids, the rate of reaction has been found to be dependent on the surface area which they expose to one another. Obviously, therefore, the rate of interaction should be effectively increased by making the particles very finely divided and then bringing about a degree of mixing as perfect as possible, which may necessitate actually grinding the materials together.
