Abstract With the orientation of potassium nitrate crystallites were fabricated below a behenic acid monolayer by using biomimetic method. The microstructure and surface topography of the obtained potassium nitrate crystallites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD data indicate that the microcrystalline is an orthorhombic crystal of potassium nitrate and grows along the (012) crystal plane. The morphology of potassium nitrate microcrystals is hexagonal with regular triangular pores. With the increase of crystallization time, the triangular pores are gradually filled, and the crystal orientation growth and crystal form remain unchanged. The results of characterization indicate that behenic acid Langmuir film can be used as a template to induce and regulate the potassium nitrate crystallites to crystallize with a special growth orientation and complex morphologries.
