WebMay 15, 2024 · Volatile matter is an unstable material. Volatile matter tends to not remain in one state and will rapidly transition to another state, or vaporize, when the right conditions are met. Volatile matter has its volatility determined not by temperature but more so by the vapor pressure required to initiate a phase change. Advertisement. WebApr 1, 2016 · At 1400 and 1450 °C, volatile matter in coal used for experiment could take the place of about 40% of fixed carbon in coal. Under the present experimental conditions, reduction product of chromium appears as FeCr 2 O 4, Cr 2 O 3, Cr 7 C 3, and [Cr] in turn during reduction.
