| 陶土主要用途 Main uses of clay 1.烧制陶器。 1. Firing pottery. 2.陶器原料。矿物成分复杂，主要由高岭石、水白云母、蒙脱石、石英和长石组成。颗粒大小不一致，常含砂粒、粉砂和粘土等。具吸水性和吸附性，加水后有可塑性。颜色不纯，往往带有黄、灰等色，因而仅用于陶器制造。 2. Raw materials of pottery. The mineral composition is complex, mainly composed of kaolinite, hydromica, montmorillonite, quartz and feldspar. The particle size is not consistent, often containing sand, silt and clay. It has water absorption and adsorption, and plasticity after adding water. The color is impure, often with yellow, gray and other colors, so it is only used in pottery manufacturing. 陶土主要用作烧制外墙、地砖、陶器具等。 Clay is mainly used for firing external walls, floor tiles, pottery ware, etc. 陶土资源主要分布在小横山一带。含矿层位主要是白垩系上部粉砂质粘土，第三纪残坡积、冲坡积，第四系上更新统戚嘴组粉质粘土。矿床（点）取样分析：含二氧化硅65.18-71.86%，三氧化二铝15.02-17.99%，三氧化二铁3.27-6.61%，氧化钙0.75-1.68%，氧化镁0.89-2.07%，烧失量4.19-6.20%。 The pottery resources are mainly distributed in Xiaohengshan area. The ore bearing horizon is mainly composed of silty clay in the upper part of Cretaceous system, residual slope deposit and alluvial slope deposit of Tertiary period, and silty clay of qizui formation of Upper Pleistocene series of quaternary system. Sampling analysis of the deposit (spot): it contains 65.18-71.86% silicon dioxide, 15.02-17.99% aluminum oxide, 3.27-6.61% iron oxide, 0.75-1.68% calcium oxide, 0.89-2.07% magnesium oxide, and 4.19-6.20% loss on ignition. |
