Department of Scientific History and Archaeometry; Graduate University of Chinese Academy of Sciences; Beijing 100049;4.Institute of Archaeology; Chinese Academy of Social Sciences; Beijing 100710; China;The fabrication technologies in terms of phase composition,structure,firing temperature,porosity,density and water permeability of ceramic water pipes and contrastive ceramic tilesexcavated from Anyang Yin Ruins of Shang dynasty were studied by X-ray fluorescence,X-ray diffraction and dilatometer,respectively.It was found that the contents of CaO,K2O,MgO and P2O5 in CWP were relatively higher than those in contrastive CT.The difference was further confirmed by the mass ratio of flux...

采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺，发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数，CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象，而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象，该结果表明陶水管原料应为一种易熔粘土，或者在沉淀粘土中人为地掺和了草木灰类掺和料，这有利于陶水管烧制与成型，有助于熔剂在熔融状态下，较好地进入陶水管中的空隙，使陶水管变得更加致密，一定程度上有利于防止陶水管的渗水，显示出陶水管制作工艺的特殊性。
