attapulgite sepiolite palygorskites thermal analysis CRTA thermogravimetry
2011/11/8
CRTA technology offers better resolution and a more detailed interpretation of the decomposition processes of a clay mineral such as sepiolite via approaching
equilibrium conditions of decomposition ...
The Steinplatte complex (Late Triassic, Northern Calcareous Alps, Austria) - subsidence-controlled development of a carbonate-platform-to-intrashelfbasin-transition
Northern Calcareous Alps Steinplatte Subsidence Rhaetian Reef Carbonate Platform
2009/10/20
Small-scale isolated carbonate mounds situated on a smoothly inclined homoclinal ramp characterized the initial phase and acted as nuclei of further carbonate buildup growth. However, only the ideal p...

Thermal dehydration of CeP3O9·3H2O by controlled rate thermal analysis
activation energy cerium phosphate controlled rate thermal analysis TG-DTA
2011/11/10
Abstract The aim of this work is to highlight the importance of controlling the residual water vapour pressure above the sample as well as the rate of the thermal decomposition during the thermal deh...
Dynamic and controlled rate thermal analysis of attapulgite
attapulgite CRTA palygorskites sepiolite thermal analysis thermogravimetry
2011/11/10
Abstract The thermal decomposition of the clay mineral attapulgite has been studied using a combination of dynamic and controlled rate thermal analysis. In the dynamic experiment two dehydration step...

Structural Changes in Analcites and Na-P Zeolites Caused by Cation Exchange at Room Temperature and Dehydration Under Controlled pH2O
Analcites Na-P Zeolites Dehydration pH2O
2011/11/16
Although zeolites are usually thought of as substances that undergo continuous water loss without structural change, there have been very few experiments to establish this fact.The present report cove...
