The high-quality copper single crystals have been successfully grown by the vertical Bridgman method(VBM),using a self-made growth furnace which is heated with four molybdenum disilicide rods.The parameters for crystal growth are typically as follows: temperature gradient at the solid-liquid interface is about 30 ℃/cm,the descending speed of the crucible is about 10 mm/d.After being polished several times,the copper crystal was analyzed by the X-ray diffraction and metallographic phase.The results show that the integrality of the grown copper crystal is good.
