| Vapor Pressure | 1 mm Hg at 3586 °C |
| Stability/Shelf Life | IF.../CHARCOAL/ IS STORED.../SRP: OPEN TO ATMOSPHERE/, IT GRADUALLY ADSORB VAPORS FROM AIR AND BECOMES WORTHLESS. |
| Autoignition Temperature | 600-750 °F |
| Heat of Combustion | 14,100 btu/lb= 7,830 cal/g= 3.28x10+5 J/kg |
| pH | Surface oxidation, which is an inherent feature of activated carbon production, results in hydroxyl, carbonyl, and carboxylic groups that impart an amphoteric character to the carbon so that it can be either acidic or basic. |
| Other Experimental Properties | The surface area, dimensions, and distribution of the pores depend on the precursor and on the conditions of carbonization and activation. Pore sizes are classified by the International Union of Pure and Applied Chemistry (IUPAC) as micropores (pore width > 50 nm), mesopores (pore width 2-50 nm), and macropores (pore width >50 nm). |
| Chemical Classes | Other Classes -> Elements, Nonmetallic |
