Ho2 B4 C1

Ho2B4C is a rare-earth boron carbide ceramic compound combining holmium, boron, and carbon in a mixed-phase structure. This is a specialty research ceramic rather than a widely commercialized material; it belongs to the family of rare-earth borocarbides and refractory ceramics that are studied for extreme-environment applications where conventional ceramics reach their limits. The material is investigated for potential use in high-temperature structural applications, neutron absorption, and advanced shielding systems where rare-earth elements provide unique nuclear and thermal properties unavailable in traditional oxide or carbide ceramics.
