    摘要: A process for producing a biocompatible implant material which can be suitably shaped into a variety of forms. A binder is added to a mixture of hydroxylapatite powder and calcium phosphate glass frit (5 wt. %), to thereby prepare a slurry, and the resultant slurry is granulated, to prepare spherical raw material granules. Separately, spherical polyisobutyl methacrylate particles are prepared, and the particles are dry-mixed with the above-prepared granules, to thereby obtain a powder mixture. The powder mixture is compacted using a mold press, to thereby form a cuboid sample. The resultant compact is heated in a drier at 170° C. for three hours, to thereby melt spherical polyisobutyl methacrylate particles. Thereafter, the compact is allowed to cool, to thereby bind the raw material granules together via the polyisobutyl methacrylate that solidifies after melting. After the compact is allowed to cool, the compact is subjected to shaping by use of a copy machining machine and also to drilling. Thereafter, the compact is heated at a rate of 300° C. hour, and fired at 1,250° C. for three hours, to thereby produce a biocompatible implant material.

    摘要: Disclosed is a method of joining metallic members together. The metallic members are coated with an undercoat composed of an alloy of tin and zinc and contacted with each other through a mixture containing a solder comprising tin and zinc and a flux, while heating the metallic members to melt the solder. Then the molten solder is solidified to join the metallic members. Here, the ratio of zinc in the undercoat is represented by x (% by weight), the ratio of zinc in the solder is represented by y (% by weight), and the ratio, x, and the ratio, y, are values within an area enclosed by the line A or B in FIG. 1, which satisfies the formulas: 1≦x≦20, 3≦y≦13 and 3≦(x+y)/2≦13, or formulas: 0.1≦x≦25, 2≦y≦15 and 2≦(x+y)/2≦15.
