The invention discloses a composite-phase ceramic evaporation boat and a manufacturing method thereof. The manufacturing method comprises the following steps of (1) preparing and mixing of materials:mixing of powders: adding zirconium silicate powder, boron oxide powder, boron nitride powder, nanometer carbon black powder, aluminum oxide and yttrium oxide powder into deionized water according toa certain ratio, adding polyvinyl alcohol as an adhering agent, forcibly stirring, and uniformly stirring, so as to obtain mixed slurry with certain viscosity; (2) drying and screening; (3) preforming; (4) sintering at high temperature. The composite-phase ceramic evaporation boat manufactured by the manufacturing method has the advantages that the room-temperature resistivity is distributed between 500 to 2000mu omega.cm; the processibility and the antioxidizing property are good; the heat conductivity is high; a heat conduction evaporation boat for a vacuum aluminum film plating technology can be manufactured, and the working life is greatly prolonged.
