1. the method for the biphase ceramics of the biphase ceramics manufacturing DCPD ceramic, DCPA ceramic, dicalcium phosphate dihydrate and oxyhydrogen-base apatite or anhydrous dicalcium phosphate and oxyhydrogen-base apatite, it is characterised in that its step includes:

  • Form a mixture, this mixture contains a phosphoric acid or an acid phosphatase salt compound and a basic calcium phosphate compound, wherein, this basic calcium phosphate compound is the oxyhydrogen-base apatite of sintering, and the choosing of this acid phosphatase salt compound freely a water one-lime phosphate, anhydrous phosphoric acid one calcium or its group formed;

    Add and add water in this mixture to form a pastel;

    Mould this pastel and become a required form, and this pastel that hardens is to obtain a solid material;

    Clean and this solid material of lixiviation, until a surface p H of this solid material reaches 4.5 or higher;

    And This solid material dry is to obtain the biphase ceramics of DCPD ceramic or dicalcium phosphate dihydrate and oxyhydrogen-base apatite at lower than 95 DEG C, or 100 DEG C or more relative superiority or inferiority dry this solid material to obtain the biphase ceramics of DCPA ceramic or anhydrous dicalcium phosphate and oxyhydrogen-base apatite;

    Wherein, when the stoichiometry of this phosphoric acid provided or this acid phosphatase salt compound equals or exceeds the percentage by weight of this basic calcium phosphate compound 0.1% to 20%, then a product is this DCPD ceramic or this DCPA ceramic;

    When the stoichiometry of this phosphoric acid provided or this acid phosphatase salt compound is less than this basic calcium phosphate compound, this product is the biphase ceramics of this dicalcium phosphate dihydrate biphase ceramics with oxyhydrogen-base apatite or this anhydrous dicalcium phosphate and oxyhydrogen-base apatite.
