Structure of heterotypic nano AIOOH microcrystals

Using RTO metal embeds cutting film micron-nano token method, the lattice fringe images of γ-AlOOH film slices were observed by high-resolution transmission electron microscopy, and the microstructure of heterotypic nano AlOOH with additive package was analyzed. It is revealed that the isomorphous replacement of iron ions and the intercalating of sulfate ions result in the lattice distortion. During crystal whisker growth, a composite polymer firstly forms, and then directionally grows; also the apolar surfactant has the functions of surface-restoring and beautifying the crystal morphology. X-ray diffraction analysis and infrared spectra are used to validate the existence of the composite polymer.
