摘要： The present invention addresses the problem of realizing bismuth sulfide which readily reflects infrared light and which has a degree of blackness that is equal to or greater than that of carbon black. The present invention pertains to bismuth sulfide particles which include aggregated secondary particles in which primary particles are aggregated, and in which the cumulative 50% diameter (D1) in a cumulative volume distribution, as measured by a laser diffraction/scattering particle size distribution measuring device is 0.2 μm to 10 μm, inclusive. Included is a step in which a bismuth compound and a sulfur compound are heated at 30° C. to 100° C., inclusive, in a dispersion medium in the presence of a protective agent.

摘要： Disclosed are an additive raw material composition and an additive for superhard material product, a composite binding agent, a superhard material product, a self-sharpening diamond grinding wheel and a method for manufacturing the same. The raw material composition consisting of components in following mass percentage: Bi2O3 25%˜40%, B2O3 25%˜40%, ZnO 5%˜25%, SiO2 2%˜10%, Al2O3 2%˜10%, Na2CO3 1%˜5%, Li2CO3 1%˜5%, MgCO3 0%˜5%, and CaF2 1%˜5%. The composite binding agent is prepared from the additive and a metal composite binding agent. The self-sharpening diamond grinding wheel prepared from the composite binding agent has high self-sharpness, high strength, and fine texture, is uniformly consumed during the grinding process, does not need to be trimmed during the process of being used, and maintains good grinding force all the time, fundamentally solving the problems of long trimming time and high trimming cost of the diamond grinding wheel (FIG. 1).

摘要： The present invention relates to a self-assembly preparation method of a nanocomposite material, and more particularly, relates to a self-assembly preparation method of a nanocomposite material comprising steps of: spraying a drug-containing solution onto metal aerosol nanoparticles to form a drug layer on the metal aerosol nanoparticles; and spraying a polymer-containing solution onto the metal aerosol nanoparticles, on which the drug layer is formed, to form a polymer layer on the drug layer, whereby since the method involves no liquid chemical process upon producing the metal aerosol nanoparticles, the processes are simple and can be performed even at a low temperature to suppress deformation of an organic or a drug, and the release rate of the drug, or the like can be easily controlled through metal types of metal aerosol nanoparticles, modification, and the like.
