The　thermal　behavior　of　coal-tar　pitch　with　different　lignin/silica　hybrid(LSH)　contents　was　studied　by　thermogravimetric　analysis(TGA).　The　optical　texture　and　micro-crystal　structure　of　resultant　cokes　from　carbonization　of　the　coal-tar　pitch　with　different　LSH　contents　were　characterized　by　reflected　polarized　light　microscopy　and　X-ray　diffraction(XRD),　respectively.　In　addition,　the　microstructure　of　resultant　cokes　was　investigated　using　scanning　electron　microscopy(SEM)and　energy　dispersive　spectroscopy(EDS).　The　results　show　that　the　thermal　stability　of　coal-tar　pitch　increases　with　the　addition　of　LSH.　Moreover,　the　addition　of　LSH　markedly　changes　the　optical　texture　and　microstructure　of　resultant　cokes.
