Coal tar is classified into three types: low-temperature coal tar, medium-temperature coal tar, and high-temperature coal tar.
Coal tar has a density fluctuating between 1.17 and 1.19 grams per cubic centimeter, translating to about 1.17 to 1.19 tons per cubic meter.
In comparison, the density of biotar typically sits at around 1.2 grams per cubic centimeter, corresponding to 1.2 tons per cubic meter.
