Previous experiments have shown that some of the rare-earth garnets become amorphous at high pressure and room temperature, [Gd.sub.3][Ga.sub.5][O.sub.12], [Gd.sub.3][Sc.sub.2][Ga.sub.3][O.sub.12], and [Y.sub.3][Fe.sub.5][O.sub.12] become amorphous at 84, 58, and 50 GPa, [31] respectively, whereas [Mg.sub.3][Y.sub.2][(Si[O.sub.4]).sub.3] in this study remains crystalline cubic up to 9 GPa.
