摘要：

Orthorhombic and rhombohedral single nanocrystalline KNbO3 with different morphologies was synthesized respectively at a relatively low temperature by simply changing the reaction solvent; a conceivable reaction process was illustrated based on the finding of a hexahedral intermediate product during the formation of KNbO3.
