The　solar　selective　absorber　coating　(SSAC)　are　at　the　core　of　the　efficient　solar-thermal　system.　In　this　paper,　for　the　first　time,　the　Chromium-iron　oxidation　mixture　cermet　was　successfully　prepared　on　the　surface　of　ultra-pure　ferritic　stainless　steel　by　chemical　coloring　as　SSAC.　The　coating　surface　has　an　optical　trap　structure,　and　the　chromium-iron　oxidation　mixture　cermet　is　used　as　an　absorption　layer　to　realize　solar-thermal　conversion.　The　solar　absorptance　(AM1.5)　of　the　coating　reached　93.66,　and　the　thermal　emittance　was　less　than　13.　After　thermal　shock　tests　at　25/300　degrees　C　done　32　times　(accumulated　812.8　h),　the　Performance　Criterion　(PC)　of　the　coating　was　0.01375　＜　0.05,　showing　outstanding　thermal　stability.
