High　temperature　resistivity　of　high　alkali　aluminoilicate　glasses　at　600-1　625°C　is　investigated　in　this　paper.　Experimental　results　show　that　the　resistivity　of　glass　melts　increases　with　the　K2O/Na2O　ratio　in　an　temperature　range　of　900-1　625°C.　The　temperature　dependence　agrees　well　with　the　Arrhenius　law,　which　implies　that　the　resistivity　of　the　glass　melt　is　controlled　by　ion　migration.　The　investigation　of　the　temperature　dependent　resistivity　of　high　alkali　aluminosilicate　glasses　show　that　the　electric　conductivity　behavior　of　glass　has　a　transition　near　900°C,　which　indicates　that　the　aggregation　degree　of　glass　network　structure　and　the　binding　force　of　modifier　ions　have　an　effect　on　glass　electrical　resistivity,　and　the　diffusion　of　alkali　metal　ions　attributes　to　the　electric　conductivity　above　900°C,　the　activation　energy　is　between　50-65　kJ/mol;　while　the　glass　conductivity　capacity　is　poor　at　600-900°C,　which　is　controlled　by　migration　mechanisms　of　alkali　metal　ions,　and　the　activation　energy　is　100-120　kJ/mol.
