Preparation of Tb
4.1 Laboratory synthesis of Tb is not feasible as the preparation of Tb requires complex technological processes.
4.2 Industrial production of Tb: Terbium is produced from xenotime and monazite mines, where it appears in the form of oxides. It is manufactured via the synthetic distillation process of Kuri-ther (also known as the Frank-Kester process).
