WebSep 13, 2024 · A good example is a sugar crystal, which contains sucrose molecules. Metallic Crystals: Metals often form metallic crystals, where some of the valence electrons are free to move throughout the lattice. Iron, for example, can form different metallic crystals. Ionic Crystals: Electrostatic forces form ionic bonds. Yttrium oxide, also known as yttria, is Y2O3. It is an air-stable, white solid substance. The thermal conductivity of yttrium oxide is 27 W/(m·K).
