Abstract:
NaBi(WO4)2 (NBW) crystals have been grown for the first time by modified-Bridgman method. Influences of some factors on the crystal growth process are discussed. X-ray powder diffraction experiments show that the unit cell parameters of NBW crystal are a=b=0.5284 nm, c=1.1517 nm, and V=0.3215 nm3. The differential thermal analysis shows that the NBW crystal melts at 923°C.
