The　dielectric　ceramics　are　being　applied　in　microwave　communication　systems,　among　them　barium　magnesium　niobates　Ba(Mg1/3Nb2/3)O-3　(BMN)　are　gaining　much　popularity.　In　this　work,　the　BMN　perovskite　ceramic　powders　are　conveniently　afforded　via　calcination　and　developed　into　porous　ceramic　pellets.　The　low　pressure　compaction　and　intermediate　temperature　sintering　is　utilized　for　the　development,　both　factors　leading　to　an　energy　economization　approach.　Thermo-analytical,　morphological　and　quantitative　B-site　order　parameter　studies　are　carried　out　for　freshly　synthesized　pure　BMN　ceramics.　Dielectric　properties　(over　the　range　of　0-1　GHz)　of　pure　BMN　pellet,　their　dependence　on　micron　size　silica　and　graphene　oxide　contents　are　extensively　studied　by　network　analyser.　Graphene　oxide　is　first　time　added　in　the　niobate　ceramic,　prepared　by　the　modified　Hummers　method.　Increase　of　silica　content　(0-2%)　is　found　to　be　directly　proportional　to　sinter-ability　of　BMN　powder,　and　in　turn,　results　in　improved　quality　factor　and　dielectric　constant.　Graphene　oxide　greatly　enhances　sinter-ability　and,　with　being　conducting　nature,　exhibits　an　unusual　increase　in　permittivity　of　the　sample　having　0.25%　graphene　oxide.
