✦ Synopsis

Degree of graphitization, average interlayer spacing, and crystallite sizes were measured on various kinds gf carbon materials. The relation between graphitization degree P, and average interlayer spacing b2 was found to show a downward deflection; the increase in P, value was retarded in comparison with the approach of the b2 value to 0.3354 nm. The deflection depended strongly on the texture of carbon samples in the nanometric scale. The existence of structural strain in carbon materials had a stronger effect on the relation to -&,l than that to PI. This is the reason why the relation between P, and m&Z shows the downward deflection.

Hydrotalcite and hydrocalumite are two close minerals belonging to the layered double hydroxide family. Both structures are based on positive brucite-like layers alternating with layers containing anions and water molecules. Most of synthetic ðLDHsÞ are hydrotalcite-like materials. On the other hand
