      Barium and lead tartrate crystals were grown in silica gel by single diffusion method. At basic pH values, barium tartrate is precipitated as a white column of colloidal particles. This column appears to move down with increasing thickness. Finally crystals develop at the expense of this white column. Lead tartrate also is initially precipitated as a column of colloidal particles in the gel. On adding acetic acid or tartaric acid over the gel, this column transforms into dendrites and later into single crystals. The development of crystals from colloidal precipitate has been explained on the basis of adsorption.

      More Details Abstract Fulltext PDF

      Interaction between clusters of silver and arsenious trisulphide have been investigated using electron diffraction and EDAX. The results of the study show the possibility of bulk reactions when clusters of two different materials are brought in contact. The chances of formation of complexes between the clusters are also considerable.
