Abstract

The possibilities and aspects of using laser ablation (LA) to study the microhemogeneity and composition of tantalum pentoxides and a Ta2O5-based lithium tantalate charge doped with small concentrations of rare earth elements (TRs) are studied. It is shown that LA can be performed for Ta2O5〈TR〉 precursor and LiTaO3ťTR〉 charge samples pelletized without a binder. The detection limits of TR are determined via inductively coupled plasma mass spectrometry (ICP-MS), and the conditions for quantitative analysis are found. Based on the calculated values of root-mean-square deviation S r , it is proved that the distribution of the dopant in the studied samples is chemically homogeneous.
