RESEARCH ON PREPARATION OF ALN FOR REFRACTORIES WITH CARBOTHERMAL REDUCTION METHOD

Yu Jianbin Wang Xinfu Liu Guoqi Yan Guangzhou(Luoyang Institute of Refractories Research,Sinosteel Corporation)  
Aluminium nitride has many excellent properties,so its application in the refractories rivets people's attention increasingly.However,high-purity aluminium nitride is very expensive which restricts its application in the field of the refractories.This paper mainly investigates the influence of the different reaction temperature,reaction time,alumina materials and particle size on the results of aluminium nitride with carbothermal reduction preparation method.The result shows that it can prepare low-cost aluminium nitride for refractories with 400 meshes Al(OH)_3 at 1500℃ for 5 hours.
