Abstract
Official abstract text for this publication.
A crystalline material contains oxygen, aluminum and phosphorus, and has powder X-ray diffraction peaks shown below. When the peak at 2θ=14.17±0.2° is used as the reference peak and the intensity of the reference peak is set to 100, for example, the relative intensity of the peak at 2θ=8.65±0.2° is 1 to 15. The relative intensity of the peak at 2θ=9.99±0.2° is 1 to 15. The relative intensity of the peak at 2θ=16.52±0.2° is 5 to 80. The relative intensity of the peak at 2θ=17.37±0.2° is 1 to 15. The relative intensity of the peak at 2θ=21.81±0.2° is 10 to 80.
