By adding silicone resin to phenolic resin as a composite binder,this paper analyzes the phase,the morphology,and the micro area composition of non-combustible alumina carbon slide plates using XRD,SEM and EDS,and discusses the effect of silicone resin on the medium temperature performance of such plates.The results indicate that silicone resin can effectively lower the fluctuation in the bulk density and apparent porosity of non-combustible alumina carbon slide plates.When 1%silicone resin is added,the plates have better overall performance.At 600℃,phenolic resin is basically dehydrogenated and carbonized,while silicone resin still has high bonding strength,which can effectively prevent such plates experiencing low strength at medium temperature.And silicone resin can promote the formation of whiskers in these plates under medium temperature conditions,thereby playing a positive role in their medium temperature performance.
