The interface bonding of coke plays an important role in improving the quality of coke.In this paper,five kinds of coking coals were mixed with weak-caking XS coals respectively to carry out crucible coke experiments.That the interface bonding index of coke decreases with the increase of par-ticle size of coal and inert content.Fat coal had good self-bonding and little influence on interface bonding index,while 1/3 coking coal and coke coal had great influence.The co-carbonization exper-iments of LF coal,XQ coal and XS coal were also carried out.Experiments show that the thermal properties of coke at high temperature were improved with the increase of interfacial bonding index.Accordingly,the microcrystalline structure was more regular,the stacking height of carbon microcrys-talline and the plane diameter of carbon net also was showed an increasing trend.
