Versuchsvorschrift

This demonstrated that there was no loss of P2O5 on firing. The powder was amorphous and was examined on an x-ray diffractometer. SEM/TEM revealed small crystals dispersed here and there in the amorphous matrix. These crystals were identified as an odd phase of AlPO4, which becomes amorphous on bombardment by the electron beam. Typical yield of this reaction was 93%. The calcined powder was white and carbon free because the starting materials contained no iron or chlorine. The product is superior in purity to aluminum phosphate produced by the reaction of aluminum chloride and phosphoric acid.
