Growth Study Of The Soft X-ray Analyzer Crystals Hydrogen Maleate 16 Ester

Hexadecyl Hydrogen Maleate (HHM) is a new kind of analyzer crystal for soft X-ray spectroscopy, with a large 2d spacing of 58.58A. HHM is hoped to give a better growth habit than octadecyl Hydrogen Maleate (OHM), because of its shorter chain length and narrower 2d spacing.In this paper, a large HHM single crystal of dimensions 60mm X 40mm X 3mm was obtained in the benzene solution by lowing the solution temperature. And considerable work has been done hi the growth behaviour in the tetrachloride solution concludingstudies of crystal growth and growth kinetics. A crystal of dimensions 20mm X 20mm X 1mm was produced hi the tetrachloride solution by lowing temperature. And BCF spiral growth mechanism for the surface diffusion model was analyzed using the kinetic data. The theoretical morphology of HHM was obtained with PBC theory. Owing to the action between the solute molecule and the solvent molecule, the theoretical morphology has some difference with the practical one. Furthermore, analytically the difference of the induction period of nucleation among different solutes or solvents was due to the difference of the solute clusters existing in the supersaturated solution.
