  • Publication number: 20220356557
    Abstract: 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 ?m or less and a proportion of fine particles smaller than 1 ?m 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 ?m and 300 ?m in opening size and collecting a powder that has passed through the 300 ?m sieve and remained on the 106 ?m 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.
