PbW3
metal· JVASP-127672· PbW3
PbW3 is a lead-tungsten intermetallic compound belonging to the family of refractory metal systems. While not widely commercialized as a primary engineering material, it represents a research-phase compound of interest for applications requiring the combined properties of tungsten's high melting point and hardness with lead's density characteristics. This material family has potential relevance in radiation shielding, high-temperature structural applications, and specialized ballistic or vibration-damping systems where extreme density and thermal stability are simultaneously required.
