- 1. A method of manufacturing bismuth germanate (Bi.sub.4 Ge.sub.3 O.sub.12) crystals, in which a starting mixture is melted in a crucible and the resulting melt being in contact with a seed crystal is moved relatively with respect to a furnace with a temperature gradient down in the direction of said temperature-gradient with such a velocity that the crystal grows from the seed crystal, characterized in that the starting mixture contains between 40.2 and 40.5 mol.% of Bi.sub.2 O.sub.3 and between 59.8 and 59.5 mol.% of GeO.sub.2.
