Abstract

Barium and calcium aluminate powders have been elaborated using chemical methods like coprecipitation, alkoxide polymerization and metalloorganic decomposition. These powders have been successfully used for impregnation of porous tungsten cathodes for use in electronic tubes. Spectroscopic studies on the modification of aluminum s-butoxide reveal that carboxylic acid substitutes OR groups forming preferentially bidentate chelating complexes.
