Metalhydrideja

Metalhydrideja is a term that appears to be a misspelling or an uncommon transliteration. The standard and widely recognized term in chemistry and materials science is "metal hydride." Metal hydrides are chemical compounds formed between metals and hydrogen. They exhibit a wide range of properties and applications depending on the specific metal involved.

These compounds can be broadly categorized into ionic hydrides, covalent hydrides, and interstitial hydrides. Ionic hydrides, typically formed by alkali and alkaline earth metals, feature a crystal lattice where hydrogen exists as the hydride ion (H⁻). Covalent hydrides, formed with more electronegative elements like boron, silicon, or elements in the p-block, involve covalent bonding between hydrogen and the central atom. Interstitial hydrides, formed by transition metals, are characterized by hydrogen atoms occupying interstitial positions within the metal lattice.

Metal hydrides are of significant interest for various technological applications. They are crucial in hydrogen storage technologies for fuel cells, offering a safe and efficient way to store hydrogen gas. Some metal hydrides are used as reducing agents in organic synthesis. Others find applications in catalysis, as getters for vacuum systems, and in the production of hydrogen. The study of metal hydrides continues to be an active area of research, with ongoing efforts to develop new materials with improved hydrogen absorption and desorption characteristics for energy-related applications.
