Abstract
NdGaO3 single crystals are joined together by filling the gap between the crystals with molten NdGaO3. The melt crystallizes according to th e orientation of the neighboring crystals. A new grain boundary is for med in the middle of the former gap, the crystals stick firmly togethe r. On the boundary many inclusions are observed, which consist of an e utectic mixture of NdGaO3 and probably Ga3Nd5O12 garnet. Etch figures of inclusion free boundary sections are comparable to those of ''natur al'' grain boundaries in NdGaO3.
