HoB2W2
metal· JVASP-155604· HoB2W2
HoB2W2 is a refractory metal boride compound combining holmium, boron, and tungsten elements, belonging to the class of ultra-high-melting ceramics and advanced refractory materials. This material is primarily of research and developmental interest rather than established commercial production, with potential applications in extreme-temperature environments where conventional superalloys and ceramics reach their limits. Engineers would consider this material family for specialized applications requiring superior thermal stability, hardness, and chemical resistance in conditions exceeding the performance envelope of nickel-based superalloys or standard carbide/oxide ceramics.
