1. , a kind of serves as the manufacture method that constitutes the polynary system ceramic powder of element with at least two kinds of metallic elements and the N that choose from Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, W, it is characterized in that, comprise:

  • will contain the powder compacting of the 1st material powder and become the molding procedure of formed body, wherein the 1st material with any of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, W as constituting element;

    For with Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, the metallic element that does not contain in any and above-mentioned the 1st material powder among the W is the above-mentioned formed body of the 2nd material contact that constitutes element, in the atmosphere that N exists, heat, when making metallic element as the formation element of above-mentioned the 2nd material be diffused in above-mentioned the 1st material, make the formation element and the N chemical combination of the 1st material, thereby above-mentioned formed body is become by the metallic element that contains above-mentioned the 1st material, the metallic element of above-mentioned the 2nd material and N are as the heat treatment step of the porous sintered article of the polynary system pottery that constitutes element;

    By being pulverized, above-mentioned porous sintered article make above-mentioned polynary system pottery become the pulverizing process of powder.
