摘要
以MgCl2·6H2O和NH4HCO4为主要原料,在添加剂空白的条件下,采用液相微波法制备MgCO3·3H2O晶须晶体,并分析了反应时间、微波辐照能量对晶体制备的影响。利用XRD、TEM等技术对制备产物进行表征。结果表明,MgCl2·6H2O和NH4HCO4混合物在微波辅助条件下反应6 min,微波辐照能量400 W时,合成的晶须结晶发育完整,晶须平均长度172μm,长径比达16.86。在此基础上,进一步探讨了微波效应与三水碳酸镁晶须晶体的生长机理。
Using the MgCl2.6H2O and NH4HCO4 as main raw materials,the MgCO3.3H2O whisker is synthesized by low-temperature aqueous solution polymerization without additive and the effect of react time and microwave irradiation power on the growth of whisker have been investigated by XRD and TEM.The results show that,when the mixture of MgCl2.6H2O and NH4HCO4 is heated by microwave under 400 W for 6 min,the average length and length-diameter ratio of completed whisker can reach 172 μm and 16.86 respectively.On the basis of this,microwave effect and the growth mechanism of nesquehonite whisker have been made further discussion.
