以氢气和氧气的燃烧为基础，研究了燃烧室内温度在焰熔法生长单晶体过程中的分布特征。结果表明，在O2的质量流量在中心处和外侧分别为5.6×10-5 kg/s和2.0×10-5 kg/s，H2的质量流量为6.0×10-6 kg/s的条件下，炉膛中心的最高温度为3007 K，金红石晶体的生长位置在距喷嘴86 mm处，晶体所能生长的最大直径为10 mm。在距炉膛入口120 mm的内炉壁的最高温度可达1540 K，需提高此区域内耐火层中刚玉粉的质量分数以提高炉壁的耐火度。

Temperature distribution in combustion chamber for preparation of single crystal with flame fusion method, which based on the hydrogen and oxygen combustion,was studied. The results showed that the maximum temperature was 3007 K at the centerline of combustion chamber when the mass flow of oxygen in the center and outer hole were 5. 6 × 10 -5 kg/s,2 × 10 -5 kg/s respectively,and the mass flow of hydrogen was 6 × 10 -6 kg/s. The optimum growth position for rutile crystal was at a distance of 86mm from the nozzle,and the maximum diameter of rutile crystal was 10mm. The quality fraction of corundum powder was increased to improve the refractoriness of refractory layer of fur-nace wall from the entrance of chamber 120mm where the maximum temperature of furnace wall was 1540K.
