摘　　要：采用常规固相反应烧结法制备了Fe2O3-MnO2-Co2O3-CuO系过渡金属氧化物陶瓷与堇青石组成的复合体系陶瓷。用红外辐射仪、XRD测定和分析了样品的红外辐射率及物相组成,同时,观察了红外辐射陶瓷外固定对兔长管状骨折断成骨活性的影响。研究结果表明,过渡金属氧化物陶瓷的常温红外辐射率达到了0.930,反尖晶石及混合尖晶石结构形成是过渡金属氧化物陶瓷中产生高的红外辐射率内在原因,在复合体系陶瓷的常温红外辐射率获得了0.920—0.930,其中过渡金属氧化物对复合体系陶瓷红外辐射性能具有决定性的作用。测定了红外辐射8—14μm波段有诱导成骨能力和加速新骨形成,促进骨缺损的修复。A composite ceramic combined Fe2O5-MnO2-Co2O3-CuO ceramic with cordierite ceramic was prepared by normal solid-phase reaction method. Infrared radiance and phase composition of the composite ceramic were characterized by infrared radiation meter and XRD. The effects of composite ceramic on osteogenesis activity were investigated as well. The results demonstrated that the infrared radiance attained 0. 930 under room temperature. The high infrared radiance of transition metal oxide ceramic resulted from structure of inverse spinel and compouded spinel. The infrared radiance of composite ceramic reached 0. 920---0. 930. The main contribition came from the transition metal oxide ceramic. The composite ceramic could induce and accelerate the new bone regeneration in wave length of 8--14 μm. It can promote repair of bone defect.
