西安交通大学与西安科技学院人员以煤矸石与弱粘煤作原料首次用Acheson工艺合成了工业SiC。实验所用硅质煤矸石及弱粘煤采用我国北方侏罗纪煤系下部煤层。经SEM研究表明:硅质煤矸石中SiO_2 Xi’an Jiaotong University and Xi’an Institute of Science and Technology coal gangue and weak sticky coal as raw materials for the first time Acheson process synthesis of industrial SiC. Experimental use of silicon and coal gangue weak stick coal in northern China Jurassic coal seam. SEM shows that: SiO_2 in silica gangue
