Highly　textured　Ca3CO4O9　ceramics　were　successfully　prepared　by　spark　plasma　sintering　using　plate-like　Ca3CO4O9　particles　synthesized　by　the　citrate　sol-gel　method.　The　microstructure　and　electrical　properties　of　the　samples　were　investigated.　The　results　show　that　spark　plasma　sintering　is　an　effective　technology　to　prepare　textured　Ca3CO4O9　ceramics　and　that　the　electrical　conductivity　of　the　textured　Ca3CO4O9　ceramics　is　anisotropic　in　various　directions.　At　700　degrees　C,　the　electrical　resistivity　of　the　sample　parallel　to　the　press　direction　is　6.13　x　10(-5)　Omega　m,　which　is　a　very　low　value　reported　so　far.　(c)　2006　Elsevier　Ltd　and　Techna　Group　S.r.l.　All　rights　reserved.
