摘要：

This　paper　studied　the　change　regulation　of　the　electrical　resistivity　of　alkali-free　boroaluminosilicate　glasses　with　the　rate　of　SrO/(CaO+SrO)　in　the　range　600~1600°C.　The　results　showed　that　a　mixed　alkaline　effect　was　observed　with　the　increase　of　SrO　content　in　alkali-free　aluminoborosilcate　glasses:　the　maximam　resistivity　of　178Ω&bullcm　appeared　at　SrO/(CaO+SrO)　ratio=0.24,　which　is　much　larger　than　108Ω&bullcm　at　SrO=0.　Meanwhile,　the　experiment　results　showed　that　the　SrO　makes　stronger　influence　on　the　resistivity　of　the　glass　than　CaO　does.　The　Arrhenius　plots,　which　showed　the　change　of　the　resistivity　with　temperature　in　range　of　1100~1625°　C,　present　nonlinear　variation,　and　an　inflection　at　about　1100°　C　It　proved　that　the　electrical　resistivity　of　the　alkali-free　aluminoborosilcate　glasses　were　controlled　by　the　ionic　radius　of　alkaline　earth　metals　and　the　viscosity　of　glass　melts.　©　(2013)　Trans　Tech　Publications,　Switzerland.
