Hafnium selenide (HfSe) is a transition metal chalcogenide ceramic compound combining hafnium and selenium. It belongs to the broader family of refractory ceramics and layered chalcogenides, primarily investigated in materials science research rather than established commercial production. HfSe is of scientific interest for high-temperature applications, semiconductor device research, and potential thermoelectric or optoelectronic applications, though it remains largely in the experimental phase compared to more mature ceramic alternatives like hafnium oxide or silicon carbide.
