Abstract

AbstractThis paper is a study from mineralogical and physico-chemical points of view about the possibility of using Arslanlar clay in tile and brick industry. Firstly, chemical analysis, X-ray diffraction (XRD), differential thermal analysis/thermogravimetry and plasticity measurements were performed to determine the unfired characterization of the clay sample. It was observed that illite, smectite, kaolinite, calcite, hematite, orthoclase and quartz were the main minerals. Plasticity tests revealed that Arslanlar clay was very high plastic clay. Then the clay test samples were prepared by pressing and firing separately at temperatures between 850° and 1100°C to evaluate physicochemical characteristics. Water absorption, linear shrinkage, bulk density, bending strength tests and colour measurement were performed. Also the fired samples were analyzed by XRD and scanning electron microscopy. It was observed that the porosity decreased and the densification increased with increasing temperature, especially above 1050°C. Evaluations concluded that this clay can be used in production of structural ceramics and also pottery.Keywords: Arslanlar clayCharacterizationMineralogyPhysico-chemical properties

具有工业应用潜力的arslar粘土的矿物学和物理化学表征

摘要本文从矿物学和物理化学的角度探讨了arslar粘土在瓦砖工业中应用的可能性。首先，通过化学分析、x射线衍射(XRD)、差热分析/热重和塑性测量来确定粘土样品的未烧制特性。主要矿物为伊利石、蒙脱石、高岭石、方解石、赤铁矿、正长石和石英。塑性试验表明，Arslanlar粘土为高塑性粘土。然后在850 ~ 1100℃的温度下分别压制和烧制粘土试样，评价其理化特性。进行了吸水率、线收缩率、容重、抗弯强度试验和颜色测定。并用XRD和扫描电镜对烧结样品进行了分析。结果表明，随着温度的升高，孔隙率降低，致密化程度提高，特别是在1050℃以上。评价结果表明，这种粘土可用于生产结构陶瓷和陶器。关键词:arslar粘土;表征;矿物学
