LSAT is the most common name for the inorganic compound lanthanum aluminate - strontium aluminium tantalate, which has the chemical formula (LaAlO₃)_0.3(Sr₂TaAlO₆)_0.7 or its less common alternative: (La_0.18Sr_0.82)(Al_0.59Ta_0.41)O₃. LSAT is a hard, optically transparent oxide of the elements lanthanum, aluminium, strontium and tantalum. LSAT has the perovskite crystal structure, and its most common use is as a single crystal substrate for the growth of epitaxial thin films.
