Abstract: Temperature distribution in growth chamber for preparation of strontium titanate single crystal with hydro-oxygen flame fusion method was investigated, and the effects of oxygen and hydrogen flow rate and aperture of nozzle on temperature distribution was analyzed. The results showed that the radial temperature and pressure at growth position of crystal decreased with the increasing of diameter. The maximal axial temperature and radial temperature of the melted cap of crystal increased with the increasing of hydrogen flow rate. With the increasing of oxygen flow rate, the radial temperature and pressure of the melted cap of crystal increased gradually in the growth chamber, while the maximal axial temperature decreased. With the increasing of oxygen aperture, the maximal axial temperature, the radial temperature and gradient decreased. The aperture of hydrogen had little effect on the axial and radial temperature in growth chamber.
