Tm1 B6

Tm₁B₆ is a rare-earth hexaboride ceramic compound combining thulium with boron in a 1:6 stoichiometry, belonging to the rare-earth boride family of refractory materials. This compound is primarily of research and developmental interest rather than established high-volume production, with potential applications in high-temperature structural ceramics, thermionic emission devices, and specialized refractory applications where chemical stability and thermal performance are critical. Rare-earth hexaborides like this are explored as alternatives to conventional refractories in extreme-temperature environments where superior oxidation resistance and thermal shock tolerance are valued over cost.
