The basic properties of alkali and alkaline earth metal phosphates calcined at various temperatures were investigated. The strength of the surface base was determined by the adsorption of acidic indicators from benzene solution. It was found that K<SUB>3</SUB>PO<SUB>4</SUB> shows a fairly high basic strength of <I>H</I><SUB>0</SUB>≥17.2. The surface basicity was evaluated by the catalytic activity for the decomposition of diacetone alcohol, which is known to be catalyzed only by basic catalysts. Comparison of the result of the activity measurement with that of TGA indicated that the basicity of a metal phosphate reaches a maximum when dehydrated completely. The nature of the basic sites on metal phosphates is also discussed.
