Barium titanate glass microspheres are used in a variety of applications, particularly for retroreflective materials, owing to their high refractive index. These microspheres can be released into the environment or found at crime scenes due to damage or decomposition. Chemical characterisation of barium titanate glass microspheres using SEM-EDX and LA-ICP-MS showed a good discrimination of the studied materials from each other. The ubiquitously used material has the potential to characterise microtraces at crime scenes or sources of anthropogenically induced particle release in environmental studies, making it a valuable feature.

钛酸钡玻璃微球的 SEM-EDX 和 LA-ICP-MS 化学表征的初步结果

钛酸钡玻璃微球由于其高折射率而具有多种应用，特别是逆向反射材料。这些微球可能会因损坏或分解而释放到环境中或在犯罪现场被发现。使用 SEM-EDX 和 LA-ICP-MS 对钛酸钡玻璃微球进行化学表征，结果表明所研究的材料之间具有良好的区分性。这种普遍使用的材料有可能描述犯罪现场的微量痕迹或环境研究中人为引起的颗粒释放的来源，使其成为一个有价值的特征。
