Abstract
In this study, the porosity and electrical resistivity of the formed coke produced by sintering the mixture of domestic anthracite and phenolic resin were mainly investigated, when the effect of the amount of binder, the hydration temperature and time, the hardening temperature and time, sintering temperature and time, the particle size of anthracite, the grade of anthracite, and the mixing ratio of phenolic resin on the physical properties of the coke were studied. As a result, It was found that the electrical resistivity and porosity of the formed coke are varied in the range of $0.3\sim1.2\Omega{\cdot}cm$ of $10\sim30%$, respectively, in accordance with the variation of factors.
