In　order　to　further　enhance　resistance　transition　temperature　(Tp)　of　metal-semiconductor　of　La-Ca-Mn-O　colossal　magnetoresistance　ceramics,　La0.67Ca0.33MnO3　(LCMO)　polycrystalline　ceramics　were　formed　as　cylindrical　pellets　(φ13　mm×8　mm)　by　conventional　solid-state　reaction　method.　The　anisotropy　of　LCMO　samples　which　was　cut　from　the　sections　parallel　and　perpendicular　to　the　pressing　direction　were　studied,　respectively.　The　R-T　curves　shows　that　transition　temperatures　for　these　two　types　of　specimens　were　177　K　and　261　K,　respectively　under　null　and　0.5　T　magnetic　field.　In　addition,　the　mechanism　of　dramatic　enhancement　of　transition　temperature　was　explained　through　investigating　XRD　and　SEM　of　the　specimens.
