Provided is an Fe—Pt—BN-based sputtering target that has a high relative density and that suppresses particle generation.

The Fe—Pt—BN-based sputtering target has, as a residue after dissolution in aqua regia measured by a procedure below, the particle size distribution in which D90 is 5.5 μm or less and a proportion of fine particles smaller than 1 μm is 35% or less. The procedure includes: (1) cutting out an about 4 mm-square sample piece from the sputtering target, followed by pulverizing to prepare a pulverized product; (2) classifying the pulverized product using sieves of 106 μm and 300 μm in opening size and collecting a powder that has passed through the 300 μm sieve and remained on the 106 μm sieve; (3) immersing the powder in aqua regia heated to 200° C. to prepare a residue-containing solution in which the powder has been dissolved; (4) filtering the residue-containing solution through a 5A filter paper specified in JIS P 3801 and drying a residue on the filter paper at 80° C. to prepare a residue powder; (5) dispersing the residue powder in water containing a surfactant to prepare a sample solution; and (6) setting the sample solution in a particle size analyzer and measuring the particle size distribution.

A process for manufacturing ceramic-metal composite material, comprises dissolving ceramic powder into water to obtain an aqueous solution of ceramic; mixing metal powder having a multimodal particle size where largest particle size is one fourth of the minimum dimension of a device, with the aqueous solution of ceramic to obtain a powder containing ceramic precipitated on the surface of metal particles; mixing the powder containing ceramic precipitated on the surface of the metal particles, with ceramic powder having a particle size below 50μ.Math.τ.Math., to obtain a powder mixture; adding saturated aqueous solution of ceramic to the powder mixture to obtain an aqueous composition containing ceramic and metal; compressing the aqueous composition to form a disc of ceramic-metal composite material containing ceramic and metal; and removing water from the ceramic-metal composite material; wherein ceramic content of the disc is 10 vol-% to 35 vol-%. Alternatively, ceramic-ceramic composite material may be manufactured.
