The Biomimetic Synthesis Of Mineral Materials

Biological mineral calcium carbonate(CaC0₃)is important in nature of the inorganic mineral materials.Due to its composition is not complex,butappear to be highly organized and structure of excellent performance,suchas strength,hardness and caused widespread interest in the study. B iological mineralization and geological mineralization is obviously different inorganic crystals are secreted by strict control of biological organic matter.It is in the organic templates induced crystallization and can grow under orderly arrangement forms the structure,excellent natural orgamc—inorganic composite materials.In this paper,under the condition of laboratory using multiple small molecules as a template for easy composite system CaC03 and BaC03 control the growth of crystal,the crystalline form and appearance diversity mechanism , specific as follows:1,Gas phase diffusion method,lysine and benzene sulfonic acid compound system of amino for raw material,through the template syhthetic condition such as reaction time,reaction to the concentration of product,the influence of product were analyzed and identified.2,Synthetic polymer has used as template and using the method of solution mixed the synthesis different BaC03 morphologies by X-ray powder diffraction(XRD),scanning electron microscopy(SEM)and infrared(IR).And the most effective syhthetic condition such as adjusting the solution of reactant ratio,the response time of different concentrations of products and SO on.3,Arginine for additive and template,through the gas diffusion was prepared by different shapes of calcium carbonate,X—ray powder diffraction(XRD),scanning electron microscopy(SEM)and infrared(IR) means of product,and discusses different reaction conditions such as concentration of reactant and solution acidity on product.
