Volatile Matter - an overview | ScienceDirect Topics

Volatile matter (VM) is the percentage loss in mass, adjusted for moisture, when coal is heated out of contact with air under standard conditions. In this test, 1 g of sample is placed into a lidded crucible (to prevent ingress of air), which is placed in a furnace at 900 °C for 7 min or 950 °C if using the ASTM method.
