The aluminophosphate molecular sieve AlPO 4 ‐5 was prepared within a reverse microemulsion under hydrothermal conditions. The resulting crystals (see picture; scale 1 μm) display a novel fiberlike morphology with aspect ratios up to 100. The 100–200 nm thick fibers are aligned with the one‐dimensional pores in the direction of the long axis of the fiber.
