We report on the modification of pre-baked clay with sodium and potassium hydroxides at 150 , 500 and 700 o C to get thermally stable intercalates.
The TG-DTA curves obtained in case of original as well as clay-NaOH and clay-KOH intercalates heated at 150, 500 and 750 o C, are provided in Figs.
It is observed that the mass loss in case of original sample is less than the mass losses observed in case of intercalates prepared at 150 o C.
The mass loss observed in case of both intercalates is quite significant.
Thus, it is inferred from the results that intercalates resulted from clay treated with NaOH gained thermal stability.
Similarly, the mass losses in case of intercalates observed at 500 and 750 o C are also quit lower than the mass losses observed in case of original clay.
2 and 3 show the DTA curves of the clay-NaOH and clay-KOH intercalates preheated at 150 o C.
In the context of a liquid metallic hydrogen model [2, 3], non-hydrogen elements reside in the layers between hydrogen hexagonal planes forming an intercalate arrangement (see Fig.
A trigger finally turned the intercalate rapidly into the gaseous phase resulting in a red giant.
Hydrogen is confined to its hexagonal planes and all other elements to the intercalate positions between the hydrogen planes.
Furthermore, exfoliation in graphite intercalate compounds  has profound consequences, regarding stellar structure and behavior.
