Thermogravimetric analysis of waxes.
Differential thermal analysis and calorimetric analysis of commercial and dental waxes have been reported in the dental literature."2 Thermogravimetric analysis is described in most textbooks on thermal analysis3-5 and is essentially a method of measuring the weight of a sample as a function of temperature or as a function of time at a fixed temperature. The purpose of this study was to examine...
متن کاملIntercalated brucite-type layered cobalt(II) hydroxysulfate
In an attempt to synthesize new cobalt(II) sulfate framework structures using 1,4-diaza-bicyclo-[2.2.2]octane as a template, crystals of poly[0.35-[hexa-aqua-cobalt(II)] [tri-μ-hydroxido-μ-sulfato-dicobalt(II)]], {[Co(H(2)O)(6)](0.35)[Co(2)(OH)(3)(SO(4))]}(n), were obtained as a mixture with [Co(H(2)O)(6)]SO(4) crystals. The crystal structure can be described as being constructed from discrete ...

متن کاملSpectral Evidence for a Brucite-carbonate Alteration Assemblage on Ceres
Introduction: The dwarf planet Ceres is the largest object in the asteroid belt and is a primary target of NASA’s Dawn mission [1]. Recent modeling has shown that Ceres is likely differentiated and consists of a thin silicate+ice crust underlain by a thicker water ice mantle [2,3]. The presence of hydrated phases on Ceres, as inferred from the 3 μm absorption feature present in surface reflecta...
متن کاملThermogravimetric kinetics of crude glycerol.
The pyrolysis of the crude glycerol from a biodiesel production plant was investigated by thermogravimetry coupled with Fourier transform infrared spectroscopy. The main gaseous products are discussed, and the thermogravimetric kinetics derived. There were four distinct phases in the pyrolysis process of the crude glycerol. The presence of water and methanol in the crude glycerol and responsibl...
