· LaC2

Lanthanum dicarbide (LaC₂) is a refractory ceramic compound belonging to the rare-earth carbide family, characterized by high hardness and thermal stability. It appears primarily in research and specialized high-temperature applications where extreme wear resistance and chemical inertness are required, such as cutting tools, wear components, and high-temperature structural applications. LaC₂ is less common in mainstream engineering than other carbides (like tungsten carbide) but offers unique advantages in niche applications demanding rare-earth properties, particularly where oxidation resistance or specific thermal characteristics provide performance advantages over conventional alternatives.
