Lanthanum Aluminum Oxide (LaAlO3)-Granules introduce:
Lanthanum aluminate is an inorganic compound with the formula LaAlO3, often abbreviated as LAO. It is an optically transparent ceramic oxide with a distorted perovskite structure.
Molar mass： 213.89 g/mol
Appearance： optically transparent, tan to brown
Density： 6.52 g/cm3
Melting point： 2,080 °C (3,780 °F; 2,350 K)
Solubility in water：Insoluble in mineral acids at 25 °C. Soluble in H3PO3 > 150 °C
Epitaxially grown thin films of LAO can serve various purposes for correlated electrons heterostructures and devices. LAO is sometimes used as an epitaxial insulator between two conductive layers.
Single crystals of lanthanum aluminate are commercially available as a substrate for the epitaxial growth of perovskites, and particularly for cuprate superconductors.
Thin films of lanthanum aluminate were considered as candidate materials for high-k dielectrics in the early-mid 2000s.
