The welding mechanism was clarified for the alumina sintered plate for thin-layer chromatography, which was made from alumina and fused glass powder mixtures, by means of scanning electron microscopic method. While the heterogeneous substances such as alumina (α=8×10^<-7>cm/cm/℃) and sodalime glass powder (α=90×10^<-7>cm/cm/℃), which are very much different in the expansion coefficient (α), are not expected to weld well with each other, the welding of these two substances does occur. The scanning electron microscopic method clearly points out that alumina is fixed among the three dimensional space formed by the sintered glass powder and the glass plate without loss of its surface structure. Thus, the sintered glass powder plays a role of the binder of alumina and the glass plate.
