In　the　paper,　regarded　SiO2-Al2O3-B2O3-RO　system　as　basic　composition,　high-temperature　glass　glaze　was　prepared　successfully　by　using　Bi2O3　in　place　of　Al2O3,　and　traditional　melt　annealing　method　was　adopted.　The　influence　of　Bi2O3　on　expansion　coefficient,　sintering　temperature,　electrical　resistivity　was　investigated　by　DIL-2008,　SJY　sintering　imager,　Keythley2410.　The　results　show　that　the　sintering　temperature　of　glass　glaze　has　a　wide　range,　which　can　reach　270　degrees　C,　so　it　is　easy　to　sinter;　with　the　increasing　of　bismuth　oxide　content,　expansion　coefficient　of　glass　glaze　gradually　increases,　whereas　sintering　temperature　and　electrical　resistivity　continuously　decreases.
