摘要：

High quality ZrB2 crystals, free of subgrain boundaries, were prepared in 0.8 MPa of helium ambient gas by the RF heated floating zone method. The optimum growth rate was 2.5-3 cm/h. The composition of the molten zone, which influenced the growth rate, was determined by the difference in vapor pressure between Zr and B elements. Helium ambient gas decreased the inclusions in the grown crystals and consequently increased the optimum growth rate, compared with the growth in argon ambient gas.
