Study on the Thermal Properties of Some Inorganically Modified Pre- Baked Clay Samples

The paper is focused on the influence of some inorganic modifiers on the thermal stability of the clay-inorganic intercalates. The inorganic modifiers used were NaOH and KOH. Solvent intercalation procedure was used. Clay was modified at 150, 500 and 750 degrees C, separately with NaOH and KOH. TGDTA study was performed to evaluate the thermal stability of the resultant intercalates. Intercalation with NaOH and KOH performed at 150 degrees C showed significant mass loss. Intercalation with NaOH performed at 500 and 750 degrees C, separately showed less mass loss compared to the ones prepared at 150 C degrees. and hence exhibited thermal stability. In case of intercalation performed with KOH at 500 and 750 C degrees, separately, the mass loss was comparable to the original pre-baked clay.
