· TaNO

TaNO is a ceramic compound combining tantalum, nitrogen, and oxygen, belonging to the family of refractory oxynitride ceramics. This material is primarily investigated for high-temperature structural applications and protective coatings where extreme thermal stability and chemical resistance are required. TaNO is notable in research and emerging applications as an alternative to conventional refractory oxides, offering potential advantages in environments combining thermal stress with corrosive atmospheres, though it remains less established in volume production than legacy refractory materials.
