    摘要： Provided is a method for producing a silver fine powder covered with an organic substance, which comprises a step of mixing (i) a dispersion of silver particles covered with a protective material X1 that comprises an organic compound having an unsaturated bond and having a molecular weight of from 150 to 1000 in a liquid organic medium A, (ii) a protective material X2 that comprises an organic compound of which the number of the carbon atoms constituting the carbon skeleton is smaller than that of the organic compound to constitute the protective material X1, and (iii) a liquid organic medium B of which the ability to dissolve the protective material X1 therein is higher than that of the liquid organic medium A, thereby promoting the dissolution of the protective material X1 in the liquid organic medium B and the adhesion of the protective material X2 to the surface of the silver particles. Accordingly, the invention provides an industrial, large-scale mass-production system for a silver fine powder covered with a protective material having a low molecular weight, of which the sintering temperature can be greatly lowered.

    摘要： A magnetic material is provided that has an iron oxide phase whose principal phase is a crystal of a structure which has the same space group as ε-Fe2O3 crystal and in which Al is substituted for a portion of the Fe sites of the ε-Fe2O3 crystal. The molar ratio of Al to Fe in the iron oxide phase, when expressed as Al:Fe=x:(2−x), satisfies 0≦x≦1. The value of x is preferably in the range of 0.3 to 0.7. The average particle diameter of the powder determined from a TEM image is preferably 5 to 200 nm, more preferably 10 to 100 nm. The magnetic material has very high practical value because it enables the extremely high coercive force Hc of the ε-Fe2O3 crystal to be regulated to a level enabling utilization in magnetic recording medium and various other applications. The magnetic powder can be produced by a method combining the reverse micelle method and the sol-gel method.
