摘要
采用X射线荧光光谱仪(XRF)、X射线衍射仪(XRD)、综合热分析仪(DTA-TG)、激光粒度仪、扫描电子显微镜(SEM)及可塑性仪对焦元坞紫砂陶土和九堡紫砂陶土的化学组成、晶相组成、热性能、粒度分布、显微形貌与可塑性进行了表征。结果表明:焦元坞紫砂陶土主要由水云母、绿泥石和石英组成,其Fe_2O_3和TiO_2含量较高,颗粒尺寸大,d50为20.25μm,可塑性指标达14.5 cm·kg(含水率为18%时),电镜下可见大尺寸云母颗粒和少量粉屑;九堡紫砂陶土主要由水云母、方解石和石英组成,其Fe_2O_3和TiO_2含量较低,颗粒尺寸小,d50为4.309μm,可塑性指标为6.7 cm·kg(含水率为18%时)。
The chemical composition, phase composition, thermal property, particle size distribution, micromorphology and plasticity ofJiaoyuanwu and Jiubao purple sand syderolite were characterized by XRF, XRD, thermal analyzer, laser particle size analyzer, SEM andplasticity instrument respectively. The results indicate that Jiaoyuanwu purple sand syderolite is mainly composed of hydromica, chloriteand quartz. Jiaoyuanwu purple sand syderolite shows high content of Fe2O3 and TiO2 and large particle size (d50=20.25 μm). And its plasticityindex can reach 14.5 cm·kg when the rate of water content is 18%. The mica particles with large size and a small amount of debris can beobserved from electron microscope. Jiubao purple sand syderolite is mainly composed of hydromica, calcite and quartz. Jiubao purple sandsyderolite shows low content of Fe2O3 and TiO2 and small particle size (d50=4.309 μm). And its plasticity index is 6.7 cm·kg when the rate ofwater content is 18%.Key words:purple sand
