Abstract
Amorphous aluminum phosphates of various compositions were prepared by a precipitation reaction, using aqueous solutions of NaH2PO4, Al(NO3) (3), and NH4OH as reagents, The resulting solids were chemically chara cterized and tested in order to observe their capability to undergo cl osed-pore formation under heating at high temperatures (above 400 degr ees C), The formation of closed pores improves the particles' light-ba ckscattering power, making them useful as white pigments.
