Abstract

Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos is partly or totally dehydroxylated, and some transformation to forsterite is observed to occur, indicative of a firing above 800 °C. Examination of freshly fractured pieces shows a nonbrittle fracture with fiber pull-out, consistent with a composite material behavior, which makes these ceramics the oldest fiber-reinforced ceramic matrix composite. Residues indicate the use of this pottery as a crucible for gold extraction using cyanide.

摘要

在科西嘉岛东北部（科西嘉角）收集的、可追溯到19世纪或更早时期的含石棉陶片，已通过扫描电子显微镜-能谱仪（SEM-EDS）、X射线粉末衍射仪（XRPD）、傅里叶变换红外光谱仪（FTIR）和拉曼显微光谱仪进行了分析。在横截面中观察到蓝色（青石棉）和白色（温石棉）石棉纤维束。大部分石棉部分或完全脱羟基，并且观察到有一些向镁橄榄石的转变发生，这表明烧制温度高于800°C。对新断裂碎片的检查显示出非脆性断裂且有纤维拔出，这与复合材料的行为一致，这使得这些陶瓷成为最古老的纤维增强陶瓷基复合材料。残留物表明这种陶器被用作使用氰化物提取黄金的坩埚。
