Abstract

PURPOSE: To make a ratio of length to diameter ≥5, by blending a raw material comprising Al and Na in a specific molar ratio of Na2O/Al2O3 with a substance of phosphoric acid in such way that P2O5/Al2O3 is made a specified molar ratio, followed by subjecting the blend to autoclave treatment under specific conditions.
CONSTITUTION: Powder of Al(OH)2 is blended and stirred with powder of AlPO4 and a solution of NaOH in such a way that a molar ratio of Na2O/Al2O3 is made 0.5W1.5. H3PO4 is added to the blend to make a molar ratio of P2O5/Al2O3 of 1W3, and subjected to autoclave treatment in a packing of 20W70% at 200W500°C, to give needle-like crystal of aluminum phosphate having a ratio of length to diameter 0f ≥5.
