Aluminophosphate (AlPO) molecular sieves (MSs) are crystalline microporous materials made from alternating PO4 tetrahedra and AlO4 tetrahedra, forming ordered channel systems and cage-like structures.

X-ray Diffraction (XRD) is a powerful inspection technology offering highly accurate material discrimination and substance identification based on an object’s molecular structure. XRD is ...

This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the spreading (diffraction) depends on how the width of the gap compares ...
