摘　　要：采用分步加热法制备出掺入Li_2CO_3含量为10wt%、17wt%的β-锂辉石样品,对两种不同Li_2CO_3掺入量的样品进行XRD及SEM的分析,结果表明:Li_2CO_3掺入量为10wt%时,致密度较高,β-锂辉石纯度低,β-锂辉石固溶体含量相对较多;Li_2CO_3掺入量为17wt%时,β-锂辉石的纯度高,气孔较多,致密性相对较差.The β-Spodumene was sythesized by step-heating method, the content of the Li2CO3 was 10wt%, 17wt%. The crystalline structure and morphology were studied by XRD and SEM, respectively. The result shows that, when Li2CO3 addition is 10wt%, the density and porosity of the β-Spodumene were small, the many solid solution of the β-Spodumene was formed, β-Spodumene was lower purity; when Li2CO3 addition is 17wt%, there is a high purity, but the density and porosity was poor relatively.
