Abstract：The high temperature adhesive was prepared using phenol-formaldehyde (PF) resin as matrix and boron carbide as additive that showed satisfied bonding properties for graphite. Subsequently, the graphite components bonded by the above adhesive were heat treated at different high temperatures. By means of X ray photoelectron spectroscopy (XPS), the composition of elements contained as well as its changes was studied, and the influences on the bonding properties were also discussed. The results show that carbon, boron and oxygen are the basic elements at bonding interface. The amorphous carbon produced from PF resin works as the framework of cements and its change has marked effects on the stability of cement. In addition, boron exists on the adhesive interface as the form of B4C or B2O3, and the existing forms have marked influence on the performance of graphite's bonding.
