利用煤矸石合成Sialon类陶瓷材料的研究进展
Research Progress of the Synthesis of Sialon Ceramic Materials by Coal Gangue
摘要
Abstract
Around the investigative progress of coal gangue used as Sialon ceramic materials,the different synthesis methods of Sialon ceramic materials have been introduced with the starting point of coal gangue waste recycling in the coal enterprises.There is a summary about the classification and chemical composition of coal gangue as well as the material condition of coal gangue to make Sialon ceramics.Some Sialon ceramic materials can be synthesized by full using of the Al2O3 and SiO2.The investigative progress of coal gangue used in synthesizing Sialon materials or Sialon multiphase materials by different synthesis methods are expatiated,and analyze these advantages and disadvantages.Several pretreatment methods of coal gangue for Sialon are listed.The technical progress of the preparation of Sialon ceramic materials by coal gangue is described,and the future development direction has been introduced.The advantages and defects of carbon thermal reduction nitriding and combustion synthesis technology are summarized.On the basis of study on modification of coal gangue and preparation of Sialon ceramics,point out problems existing in the process of industrialization.The future research direction and focus as well as suggestions existing in the synthesis technology which are necessary to overcome have been put forward.关键词
