In　this　paper,　TiO2　is　added　to　CaO-SrO-B2O　3-SiO2　sealing　system　to　tailor　the　sealing　properties　of　glass-ceramic　seals.　The　coefficient　of　thermal　expansion　(CTE)　of　quenched　glasses　and　glass-ceramics　(held　at　750　C　for　100　h)　does　not　change　significantly　with　the　addition　of　TiO2;　whereas,　the　glass　stability　(ΔTxg　=　Tx　-　Tg)　decreases　systematically　with　increasing　TiO2.　The　addition　of　TiO2　accelerates　the　crystallization　of　sealing　glasses.　The　formation　of　Sr-containing　phase,　e.g.,　Sr(TiO3),　contributes　to　the　improved　chemical　compatibility　as　well　as　the　increase　in　conductivity　of　sealing　glasses　(e.g.,　from　7.9　×　10-8　S　cm-　1　to　6.9　×　10-5　S　cm-　1　at　800　C).　In　addition,　the　good　bonding　is　observed　at　the　interface　between　Cr-containing　interconnect　(430SS)　and　glasses　containing　4-8　mole　%　TiO2,　held　at　750　C　for　100　h.　©　2013　Elsevier　B.V.　All　rights　reserved.
