摘要：

Low-temperature　co-fired　ceramic　(LTCC)　technology　can　meet　the　requirements　of　device　miniaturization　and　integration.　In　this　work,　a　novel　series　of　CaMoO4　+　x　wt.%　Li2MoO4　(CMO+　xLMO,　x　=　0.0-2.5)　microwave　dielectric　ceramics　were　prepared.　The　sintering　temperature　of　CMO　ceramic　significantly　declines　from　1050　degrees　C　to　600　degrees　C　by　adding　a　small　amount　of　LMO.　A　dissolution-precipitation　process　at　the　grain　boundary　has　been　demonstrated　to　be　the　mechanism　for　low-temperature　sintering　through　transmission　electron　microscopy　analysis.　The　low-temperature　sintered　CMO　ceramics　present　excellent　microwave　dielectric　properties,　e.g.　CMO+　1.0　wt.%　LMO　ceramics　sintered　at　600　degrees　C,　er　-　14.4,　Qxf　-　13,060　GHz,　rf　-　-　41.0　ppm/degrees　C;　CMO+　2.5　wt.%　LMO　ceramics　sintered　at　700　degrees　C,　epsilon　r　-　15.1,　Qxf　-　16,122　GHz,　rf　-　-　43.8　ppm/degrees　C,　which　show　great　potentials　in　both　LTCC　and　ULTCC　applications.
