摘要

Abstract

Herein

three kinds of Li

and two kinds of MgCO

·3H

O crystals are easily synthesized in a homogeneouslike organic phase. The morphology and size of synthesized crystals are controllable and adjustable in the single organic phase

with the morphology of Li

ranging from micro-flaky

flower to nanobranch

MgCO

·3H

O ranging from nanosphere to nanorod. Compared with coupled reaction and solvent extraction process

of which the crystallization process occurred in the interface of two phase

our proposed method made it possible that the crystallization process occurred in the single organic phase

which resulted in better crystal morphology. Moreover

the formation mechanism of different crystal morphologies is discussed

the results showed that the crystals in micron size and nano size are involved in two crystallization mechanism

the micron particles in the form of flake and flower-like is a typical radial growth

which means that the growth occurs by diffusion around a nucleus as starting point

while the reaction model for small particles should be similar to a water-in-

oil structure. As the reaction carried out

the crystal should be restricted in a constrained organic structure.
