Abstract

The current study investigates the effect of adding a low-cost biomaterial (sawdust biomass) to kaolinite clay on the properties of insulating refractory materials. Natural kaolinite clay from NW Tunisia has been selected for porous ceramic preparation due to its high alumina content (23.64%) with low impurities, especially iron and alkaline oxides. For this study, a set of cylindrical samples were prepared from mixtures of Tabarka clay with different proportions of sawdust (10, 15 and 20%). Those green specimens were pressed and sintered to 1350 °C for 2 h. Experimental data showed that the increase in sawdust proportion increased the open porosity from 24 to 35%. SEM images showed higher important porosity with higher biomass addition. Similarly, bulk density and compressive strength decreased to 1.65 g/cm3 and 17 MPa, respectively. Mullite phase was also generated by the abundant alumina and silica in the raw feed. Several ceramic specimens were also manufactured under optimal conditions: sawdust (20%), pressure (10 kN), and sintering at 1200, 1250 and 1300 °C. The obtained ceramics showed higher porosity (57%), but lower bulk density (1.13 g/cm3). These are the required standards for silica-alumina insulating materials, confirming the possible valorization of kaolinite clay from Tunisia for refractory insulating ceramic.

用于耐火陶瓷制造的生物质-天然混合高岭石
本研究探讨了在高岭石粘土中添加低成本生物材料(锯末生物质)对绝缘耐火材料性能的影响。突尼斯西北部的天然高岭石粘土因其氧化铝含量高(23.64%)、杂质少(尤其是铁和碱性氧化物)而被选为制备多孔陶瓷的原料。在这项研究中,我们用塔巴卡粘土与不同比例(10%、15% 和 20%)锯屑的混合物制备了一组圆柱形样品。实验数据显示,锯屑比例的增加使开放孔隙率从 24% 增加到 35%。扫描电镜图像显示,生物质添加量越高,重要孔隙率也越高。同样,体积密度和抗压强度分别降至 1.65 克/立方厘米和 17 兆帕。原料中丰富的氧化铝和二氧化硅也产生了莫来石相。在锯屑(20%)、压力(10 kN)和 1200、1250 和 1300 °C 烧结等最佳条件下,还制造出了几种陶瓷试样。获得的陶瓷孔隙率较高(57%),但体积密度较低(1.13 克/立方厘米)。这些都是硅铝绝缘材料所要求的标准,证实了突尼斯高岭石粘土在耐火绝缘陶瓷中的应用价值。
