Determination of the true density of pulverized coal samples

The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight of the sample. The method is similar to that used to determine the density of refractory materials but the procedure is modified to yield precise density determinations of coal …
