Abstract: The crystal of BSO was grown at a spacecraft for the first time. The space-grown and terrestrially-grown BSO crystals were measured by X-ray rocking curves and dislocation etchings as well as transmission spectra. The results show that the optical qualities of space-grown BSO crystal can be highly improved under microgravity.

Key words: bismuth silicon oxides (BSO), crystal growth, Bridgman method microgravity
