    摘要： Provided is a method of producing porous silica-based particles with the relatively larger average diameter of 1 micron or more and also having a low particle density. The method comprises the steps of (a) preparing two-layer separated liquid consisting of an organic silicon compound layer and a water layer, then adding an organic solvent, an alkali, and a surfactant into the water layer while agitating at least the water layer so that the organic silicon compound layer and the water layer are not completely mixed with each other, further hydrolyzing and/or partial hydrolyzing the organic silicon compound in the mixed aqueous solution to prepare silica-based particle precursors, (b) adding sodium aluminate into the mixed aqueous solution containing the silica-based particle precursors and then preparing silica-based particles having pores, cavities or voids inside the particles, and (c) washing and drying the silica-based particles. Thus obtained particles are useful for various applications such as microcapsules, adsorbents, catalysts, low refractive film, low dielectric film and low reflectivity film.

    摘要： The present invention provides a method of forming on a substrate a particle layer highly adherent to the substrate, which comprises the steps of spreading a dispersion (I) comprising a dispersing medium and, dispersed therein, solid particles being surface treated with a compound acting as a binder on a liquid (II) having a specific gravity higher than that of the dispersing medium, said liquid (II) being immiscible with the dispersing medium, subsequently removing the dispersing medium from the dispersion (I) to thereby arrange the solid particles on the liquid (II) so that a particle layer is formed on the liquid (II) and thereafter transferring the particle layer onto a substrate. Moreover, the present invention provides a method of planarizing an irregular surface of a substrate, which comprises transferring the above particle layer to an irregular surface of a substrate and removing parts of the particle layer formed on protrudent parts of the substrate to thereby planarize the irregular surface of the substrate and also provides a particle-layer-formed substrate comprising a substrate and, superimposed on a surface thereof, the particle layer obtained by each of the above methods.
