· JVASP-58195· NiW2O8

NiW₂O₈ is a nickel tungsten oxide ceramic compound belonging to the mixed-metal oxide family. While not a mainstream engineering material, it represents a class of refractory and functional ceramics studied for applications where tungsten's high melting point and nickel's catalytic or electronic properties may be leveraged. The material's primary interest lies in research contexts exploring thermal stability, electrical functionality, or catalytic behavior in high-temperature or corrosive environments.
