The capability of this workflow was extended further in an exploration of the Nb-Al-P-O system. It is possible to cover over 80% of the chemical space (Fig. ) using the starting materials Nb2O5, Al2O3, AlPO4, Nb2P4O15, and a commercial niobium phosphate (CBMM, Brazil) with a P/Nb ratio of 0.65. The remaining 20% of the phase diagram is not accessible by this method as it requires the use of P2O5 which is water soluble. 149 individual samples spanning the forty-six compositions within the Nb-Al-P-O phase field shown in Fig. were prepared using appropriate mixtures of the starting materials, calcined at four temperatures (1000 °C, 1100 °C, 1200 °C or 1300 °C) and characterised by X-ray diffraction in a three week period; the researcher was engaged in other tasks during this period. The known ternary compositions Nb50Al2O128, Nb18Al2O48 and Nb9PO25, and the Nb3AlP6O24 quaternary (Fig. ) reported by Zhao et al were detected demonstrating that the raw materials do react when processed as described to replicate outcomes previously obtained by conventional solid state processing, affording oxides, phosphates and phosphate oxides with complex structures.
