· Yb4 Be4 Si4 Ni2 O20

Yb₄Be₄Si₄Ni₂O₂₀ is a complex mixed-metal oxide ceramic combining rare-earth (ytterbium), lightweight (beryllium), silicate-forming (silicon), and transition metal (nickel) elements. This compound represents specialized research-phase ceramic chemistry rather than a commodity material, likely explored for high-temperature structural or functional applications where the combination of rare-earth stability, beryllium's low density, and silicate-based bonding offers potential advantages over conventional alternatives.
