Homogenized mixtures of copper, gallium, and sulphur were annealed for 200 hrs. under vacuum at about 1000–1050°C (i.e. below the melting point of the CuGaS 2 phase) in quartz ampoules in a vertical position, and then cooled down in a temperature gradient. The final charge was made up of three well‐defined portions: a yellow polycrystalline CuGaS 2 with large blocks of CuGaS 2 (close to stoichiometry), a black portion with darkgreen aggregates of small CuGaS 2 crystals, and yellow laminae of CuGaS 2 single crystals, slightly inclined away from [112] direction. — A coupled growth mechanism — solidstate‐diffusion‐assisted coalescence/vapour transport — is assumed.
