Yttrium and pnictides can form compounds with the chemical formula YE (E = N, P, As, Sb). They can be hydrolyzed in humid air and emit volatile hydrides EH 3. Yttrium and carbon can form a variety of compounds, such as Y 2 C 3, [9] YC 2. [10] They can be made in several ways: 2 Y + 3 C → Y 2 C 3 Y 2 O 3 + 7 C → 2 YC 2 + 3 CO ↑
Yttrium, iron, aluminium, and gadolinium garnets (e.g. Y 3 (Fe,Al) 5 O 12 and Y 3 (Fe,Gd) 5 O 12) have important magnetic properties. [15] YIG is also very efficient as an acoustic energy transmitter and transducer. [74] Yttrium aluminium garnet (Y 3 Al 5 O 12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated ...
Y 2 O 3 is used to make the high temperature superconductor YBa 2 Cu 3 O 7, known as "1-2-3" to indicate the ratio of the metal constituents: 2 Y 2 O 3 + 8 BaO + 12 CuO + O 2 → 4 YBa 2 Cu 3 O 7. This synthesis is typically conducted at 800 °C.

Although YBa 2 Cu 3 O 7 is a well-defined chemical compound with a specific structure and stoichiometry, materials with fewer than seven oxygen atoms per formula unit are non-stoichiometric compounds. The structure of these materials depends on the oxygen content. This non-stoichiometry is denoted by the x in the chemical formula YBa 2 Cu 3 O 7 ...
Yttrium(III) nitrate is mainly used as a source of Y 3+ cations. It is a precursor of some yttrium-containing materials, such as Y 4 Al 2 O 9, [3] YBa 2 Cu 3 O 6.5+x [2] and yttrium-based metal-organic frameworks. [5] It can also be used as a catalyst in organic synthesis. [6]
A molecular formula enumerates the number of atoms to reflect those in the molecule, so that the molecular formula for glucose is C 6 H 12 O 6 rather than the glucose empirical formula, which is CH 2 O. However, except for very simple substances, molecular chemical formulae lack needed structural information, and are ambiguous.
