· TmAsO3

TmAsO3 is a rare-earth arsenate ceramic compound containing thulium, arsenic, and oxygen. This material belongs to the family of lanthanide arsenates, which are primarily of research interest for their crystallographic and potential photonic properties rather than established commercial applications. The compound and related lanthanide arsenates are investigated in materials science for their thermal stability, optical behavior, and potential use in specialized ceramic systems, though practical engineering applications remain limited and largely experimental.
