摘要：

By using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), the measurement of particle size has been made for one component oxide (Al2O3 and MgO) and multicomponent oxide (12CaO.7Al(2)O(3) and CaO-Al2O3-Mgo) located on surface of iron or glass sample, The method of particle size estimation by LA-ICP-MS has been developed coupled with a new method of making samples with particles. The size calibration lines for Al2O3, MgO and CaO particles have been obtained. The results of particle size measurement by LA-ICP-MS are compared with those by SEM and single-particle optical sensing (SPOS) methods. It was confirmed that LA-ICP-MS has the perspective to be used for the quick measurement of inclusion composition and size in metal and other materials. The size frequency distributions of Al2O3 particles measured by LA-ICP-MS in iron samples with particles agree reasonably well with those by SEM and SPOS in the range of particle diameter from 2 to 20 mum. The size of Al2O3, MgO and complex oxide (12CaO.7Al(2)O(3) and CaO-Al2O3-Mgo) particles measured by LA-ICP-MS is in good agreement with that by SEM in the range of particle diameter from 10 to 40 mum.
