实验室,北京 100190) 摘 要:主要从固相法和液相法两个方面介绍铬盐生产工艺中铝杂质的脱除方法,固相法重点介绍无钙焙烧法,无钙焙烧熟料中含铝固相产物有铁镁矿(Mg(Fe,Al)2O4),铝硅酸钠(NaAlSiO4)和铝硅酸镁钠(Na4MgAl2Si3O12).同时,根据铬矿成分的不同,添加含硅或含铝原料,控制SiO2和Al2O3摩尔比,使铬铁矿中的铝和硅在无钙焙烧过程中转化成为铝.... The special emphasis was placed on lime free roasting process. Magnesioferrite (Mg(Fe,Al)2O4), sodium aluminosilicate (NaAlSiO4), silicic acid, aluminum magnesium sodium salt(Na4MgAl2Si3O12) are the major......
着界面层厚度的增加,特别是当镀层本身热导率较低时,材料的热导率将降低,若镀层厚度趋近于零,则材料的热导率将会很高.但镀层厚度过低将导致界面结合力下降.Ni,TiC,Mo2C,SiC和Si等镀层可显著提高复合材料的热导率,而Ag镀层对复合材料导热性能则会产生不利影响.WU等[54]发现,合适的Ti镀层能够有效提高界面结合力和diamond/Al复合材料的抗拉强度.TAN等[55]对金刚石表面镀W,利... and development of high silicon aluminium alloy for light weight electronic package materials[J].

Introduction Interest in alloy and cermet materials for fabricating inert anodes for use in industrial aluminum electrolysis has increased in recent years because of their significant advantages in terms..., it leads to lowering of the collision frequency (n) and vj in Eqs. (6) and (8), while the volume of the mill pot remains constant. The value of mg in Eq. (5) is also very large. It can be seen from......
