In recent years, organoclays have become widely used in many industrial applications, and particularly they have been applied as adsorbents for water purification (de Paiva et al., 2008; Zhou et al., ...
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 ...
Organoclays are the adsorption products of organic matter by clay minerals. In modern technology, organoclay-based nanocomposites obtained by modifying Na-clay by primary adsorption of organic ammoniu...
The thermal behavior and decomposition of kaolinite–potassium acetate intercalation complex was investigated through a combination of thermogravimetric analysis and infrared emission spectroscopy. Thr...
The thermal analysis of euchroite shows two mass loss steps in the temperature range 100–105 °C and 185–205 °C. These mass loss steps are attributed to dehydration and dehydroxylation of the mineral. ...
Insight into the unique structure of layered double hydroxides (LDHs) has been obtained using a combination of X-ray diffraction and thermal analysis. Indium containing hydrotalcites of formula Mg4In2...
Three halotrichites namely halotrichite Fe2+SO4·Al2(SO4)3·22H2O, apjohnite Mn2+SO4·Al2(SO4)3·22H2O and dietrichite ZnSO4·Al2(SO4)3·22H2O, were analysed by both dynamic, controlled rate thermogravimetr...
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...
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...
Thermal degradation of granite and marble industry reject (GMIR), a red clay (RC)and their composites were studied by non-isothermal thermogravimetry (TG/DTG) in nitrogen atmosphere, differential ther...
A series of sepiolites, palygorskites and “Rocky Mountain Leather” clay minerals have been analysed by controlled rate thermal analysis and differential scanning calorimetry. Eight weight loss steps a...
Abstract: Samples containing spherical kaolinite, synthesized under hydrothermal conditions (T = 200 癈; t = 24 h, 192 h, 720 h) from gel with Si/Al = 0.84, were studied by differential thermal analysi...
Platy (Te Puke, New Zealand), cylindrical (Spruce Pine, North Carolina), and spherical (North Gardiner mine, Huron, Lawrence County, Indiana) halloysite samples were analyzed by high-pressure differen...
The enthalpy of freezing of methyl salicylate sorbed by four commercial montmorillonite clays was used to estimate the absorption/adsorption capacity of the clay. Differential thermal analysis was the...
A semi-micro quantity (10–15 mg) sample of clay is pressed into a 3 mm diameter pellet for differential thermal analysis (DTA) in a STONE-TRACOR ring microsample holder. The pellet is transferred to t...
