- Punika digugat ing Manufaktur Paint kimia lan Manufaktur kaca.
- Senyawa saka logam beracun; nanging isih barium sulfat punika insoluble lan diwenehi kanggo patients gerah saka kelainan pencernaan.
- Dysprosium logam reaktif amarga kang wangun murni ora minangka biasanipun minangka alloy sawijining.
- Thi alloy logam digunakake ing magnate iku resistance kanggo suhu dhuwur.
