is preferentially being deposited at the external surface, thus blocking the micropores. The effect of impregnation on the porous texture increases as the synthesis temperature decreases and results in the significant rise in the micropores contribution to the total porosity. Furthermore, the comparison of dried and fired samples reveals that the initial characteristics of porous texture are not considerably affected by thermal treatment. These results evidence the good thermal stability of titania–alumina support.

The values of porous texture parameters are summarized in Table 1. It is found that the average width (d ) of slit-shaped pore is in good agreement with the mean size of micropores obtained from the intersection of the two straight lines of the t-plot. This result indicates clearly that the micropore are slit-shaped. Furthermore, it is of interest to note that the majority of parameters characteristic of porous texture increases by increasing the synthesis temperature or by decreasing the complexing ratio. As the more pronounced change in texture is induced by synthesis temperature, we have choice to study the effect of this experimental parameter on the catalytic activity of titania–alumina-supported molybdenum catalyst.

Synthesis and characterization of alumina/carbon nanotube (CNT) composite powders have been investigated for production of nanotube reinforced ceramic composites. The alumina/CNT powder was prepared by catalytic decomposition of acetylene gas with iron supported on alumina. The catalyst source was iron nitrate and the iron content was controlled up to 5.0 mol % to change the CNT compositions in the composite powders. The nanotube content in the powders was determined by an elemental analyzer. The quantity and quality of the CNT in the powders have been investigated with SEM, TEM, XRD and BET. The content of CNT was increased up to 12.5 wt. % and the CNT diameter increased with increasing iron catalyst content. The surface area and carbon content analysis shows that the quality of CNT is highest at 1.0 mol % iron catalyst loading. The synthesized CNT was fairly well-dispersed in the alumina powder.

B-alumina is a sodium ion conducting solid electrolyte with an ideal formula Na20.1 1 A1203. It hasanother phase namely 8" alumina (Naz0.5AI2O3) wherein Na20 content is more and has a greaterconductivity than beta A1203. Distinctions between B and 8" A1203 are given in this paper. Variousmethods of synthesizing the above powders and sintering to gel one end closed tubesare discussed herefor their use in sodium-sulphur batteries
