    摘要: This patent describes economical and environment-friendly processes for the synthesis of Al-containing non-Mg anionic clays. It involves hydrothermally reacting a slurry comprising a divalent metals source with a trivalent metals source to directly obtain Al-containing non-Mg anionic clay, at least one of the metal sources being an oxide, hydroxide or a carbonate. There is no necessity to wash or filter the product. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. The product can be combined with other ingredients in the manufacture of catalysts, absorbents, pharmaceuticals, cosmetics, detergents, and other commodity products that contain anionic clays.

    摘要: In a method for producing PLZT powder, the A-site components are co-precipitated simultaneously and mixed with the B-site components which are also co-precipitated simultaneously. As a result, the powder obtained by calcination of the precipitates has less fluctuation in the chemical composition compared with the prior art.
