Increasing the Effectiveness of Aluminium Phosphate Binders
A method is presented for more than doubling the volume yield from an AlPO4 precursor, aluminium chlorophosphate ethanolate, from approximately 20% to 50% by replacing the ethanol ligands with water. It is shown that this increases the volume yield from about 20% to 50%. The precursor is used to make an Al2O3 powder bonded with an amorphous AlPO4 with a Young modulus of 80 GPa and a strength of 60 MPa.
