In the case of the normal spinel structure, divalent cations occupy in A site (Tetrahedral) and trivalent cations occupy in B site (Octahedral).
Moreover, a single crystal structure is formed when the synthesis temperature is 95°C.
The obtained materials have partially inverse structures spinel.

Influence of Calcining Temperature on the microstructure of LaPO4 powders Zifeng Liu1,2,a, Xin Wang 2,b , Yansheng Yin1,2,c, Qiang Liu2,d 1 College of Chemistry and Chemical Engineering, Ocean University of China, Qingdao 266100, People's Republic of China 2 Institute of Materials Science and Engineering, Ocean University of China, Qingdao 266100, People's Republic of China a lzfi@163.com, bwangxinhd@ouc.edu.cn, cyys2003@ouc.edu.cn, dliuqiang1985@tom.com Keywords: LaPO4; calcining temperature; direct precipitation method; monazite Abstract.
The calicined powders were characterized by X-ray powder diffraction (XRD) and Scanning Electron Microscope (SEM), and exhibited a pure LaPO4 phase with a monazite structure about 50-100 nm in diameter size.
All peaks in three patterns could be indexed as a monoclinic LaPO4 with a monazite structure.
