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. Moisture in the analysis sample is determined concurrently.
