What is Thermogravimetric Analysis of Selected Coal-bearing Strata Kaolinite about?
Two kinds of coal-bearing kaolinite from China were analysed by X-ray diffraction (XRD), Thermogravimetric analysis-mass spectrometry (TG-MS), infrared emission spectroscopy. Thermal decomposition occurs in a series of steps attributed to (a) desorption of water at 68 • C for Datong coal-bearing strata kaolinite and 56 • C for Xiaoxian with mass losses of 0.36% and 0.51%, (b) decarbonization at 456 • C for Datong coal-bearing strata kaolinite and 431 • C for Xiaoxian kaolinite, (c) dehydroxylation takes place in two steps at 589 and 633 • C for Datong coal-bearing strata kaolinite and at 507 and 579 • C for Xiaoxian kaolinite. This mineral was further characterised by infrared emission spectroscopy (IES). Well-defined hydroxyl stretching bands at around 3695, 3679, 3652 and 3625 cm -1 are observed. At 650 • C all intensity in these bands is lost in harmony with the thermal analysis results. Characteristic functional groups from coal are observed at 1918, 1724 and 1459 cm -1 . The intensity of these bands decrease by thermal treatment and is lost by 700 • C.
