thermal stability of kutch bentonite

Thermal stability of some industrial bentonites ...

1991-3-1  The thermal stability graphs seem to show this relationship somewhat better (Fig. 4), but they also show better thermal stability for a sodium-exchanged calcium bentonite. Hoffman's theory, that the iron-magnesium ratio of the clay structure influences durability cannot be shown by these results.

STUDY OF THERMAL AND ACID STABILITY OF

The thermal and acid stability of the bentonite clays (Na- and Ca-bentonite) have been tested. The thermal stability testing has been carried out by heating 5 gram of the clays for five hours at 200, 300 and 500 °C respectively, meanwhile acid stability testing was performed by immersing 5 gram clays into 100 mL sulphuric acid 1M, 2M and 3M for 24 hours.

Thermal Stability of Bentonites in Foundry Molding

The effects of heat on the behavior of sodium and calcium bentonite in bonding foundry sands were studied. Tests such as differential thermal analysis, viscosity, and melting or vitrification temperatures do not indicate the suitability of a bentonite for foundry use. The deterioration temperatures of sodium and calcium bentonite are 1180° and 600°F respectively.

Thermal analysis of foundry bentonites - Politechnika Śląska

A thermal stability of bentonite, in principle its main component – montmorillonite – as well as changes in microstructure decide on the bentonite suitability for foundry practice. The temperature influence causes gradual loosing of the bentonite binding properties due to dehydroxylation (at temperatures 500-600oC),

Thermal and chemical stability of Romanian bentonite ...

Ca–bentonite originating from a Romanian deposit was leached in 0.5–8.0 M HCl solution at 90 °C for 4 h. This material was fully characterized through BET, thermogravimetry, X-rays diffraction, and elemental analysis. The acid treatment at high temperature altered the crystallinity, but produced an increase in the surface area and thermal stability.
