STISHOVITE is the highest pressure polymorph of silica. It possesses the rutile structure with a density of 4.28 g cm−3 and is characterised by sixfold coordination of silicon by oxygen. Previous structural studies1–3 of stishovite have been based on powder diffraction data. However, complete definition of its crystal structure requires single crystal studies. We have, therefore, undertaken a programme to synthesise single crystals of high pressure phases. We report here the successful synthesis of single crystals of stishovite up to 230 µm in length, and describe its crystal structure.
