Effects　of　BiVO4　addition　on　the　sintering　behavior,　crystal　structure,　microstructure　and　microwave　dielectric　properties　of　CaLa4Ti4O15　ceramics　were　investigated.　When　BiVO4　addition　is　below　3　%,　the　sintering　temperature　of　CaLa4Ti4O15　ceramics　is　reduced　from　1,550　A　degrees　C　to　about　1,400　A　degrees　C.　And　only　phase　CaLa4Ti4O15　is　observed　in　the　CaLa4Ti4O15　ceramics.　However,　the　secondary　phase　CaLa4Ti5O17　appears　when　BiVO4　addition　reached　3　%.　It　is　important　that　a　small　amount　of　BiVO4　addition　can　not　only　lower　the　sintering　temperature　but　also　improve　the　microwave　dielectric　properties　of　CaLa4Ti4O15　ceramics.　The　CaLa4Ti4O15　ceramics　with　1.0　%　BiVO4　addition,　which　is　sintered　at　1,425　A　degrees　C,　exhibits　excellent　microwave　dielectric　properties　of　epsilon　=　44.3,　Qf　=　51,377　GHz,　tau　(f)　=　-9.0　ppm/A　degrees　C.　The　variation　of　microwave　dielectric　properties　had　been　also　discussed　with　the　structure　evolution.
