Abstract Latosols are part of the soil group with the widest geographic distribution in Brazil. This soil type consists of a yellowish to reddish clayey material, and it has been widely studied for its applicability to agriculture in tropical zones. Because of the wide distribution and mineral composition of latosols, it is important to evaluate the technical feasibility of using these materials for the production of red ceramics. The raw materials were characterized using X-ray diffraction, thermogravimetric and differential thermal analysis, inductively coupled plasma mass spectrometry, inductively coupled plasma optical emission spectrometry, scanning electron microscopy, and a laser particle analyzer. To determine the physical and mechanical properties, 20 different mixtures of samples were produced with the latosols of Rondon do Para and Mosqueiro combined with 0, 20, 30, and 40% illitic or gibbsitic clays; each composition was calcined at 950 and 1100 °C. The technological properties of the samples (linear shrinkage, water absorption, apparent porosity, apparent density, and flexural strength) were investigated. The Mosqueiro latosol consists of quartz and kaolinite with additional minerals of anatase and goethite, whereas the Rondon latosol contains kaolinite and quartz as the dominant minerals, as well as goethite, anatase, and gibbsite. Only the Mosqueiro latosol, without the addition of other materials, demonstrated technological aspects that were favorable for its use in the production of ceramic products. However, the addition of illitic and gibbsitic clays significantly improved the technological characteristics of the two latosols studied.

用黄色亚马逊土溶胶与伊利石和三水铝石粘土烧结红色陶瓷

摘要 Latosols 是巴西地理分布最广的土壤群的一部分。这种土壤类型由淡黄色至红色粘土组成，因其在热带地区的农业适用性而被广泛研究。由于 latosols 的广泛分布和矿物组成，评估使用这些材料生产红色陶瓷的技术可行性非常重要。使用 X 射线衍射、热重和差热分析、电感耦合等离子体质谱、电感耦合等离子体发射光谱、扫描电子显微镜和激光粒子分析仪对原材料进行表征。为了确定物理和机械性能，使用 Rondon do Para 和 Mosqueiro 的 latosols 与 0、20、30 和 40% 伊利石或三水铝石粘土组合生产了 20 种不同的样品混合物；每种组合物在 950 和 1100 °C 下煅烧。研究了样品的技术性能（线性收缩率、吸水率、表观孔隙率、表观密度和弯曲强度）。Mosqueiro latosol 由石英和高岭石以及其他矿物质锐钛矿和针铁矿组成，而 Rondon latosol 包含高岭石和石英作为主要矿物，以及针铁矿、锐钛矿和三水铝石。只有 Mosqueiro latosol，在没有添加其他材料的情况下，展示了有利于其用于生产陶瓷产品的技术方面。然而，
