    摘要： The present invention relates to a method of preparing ultra-pure silicon carbide in which a super-porous spherical silica aerogel is used as a silica raw material, wherein a reaction area with respect to a carbon raw material is increased to enable low-temperature synthesis of silicon carbide, the size and shape of silicon carbide powder may be uniformly controlled to prepare ultra-pure silicon carbide, economic efficiency and productivity of the silicon carbide synthesis may be improved by preparing the silica aerogel particles using low-cost water glass, and thus, it is expected that the silicon carbide powder prepared by the preparation method of the present invention may be provided as an optimized raw material for the preparation of silicon carbide sintered body and single crystal (ingot).

    摘要： The present invention relates to an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific period of time to control fluidity while achieving a viscosity at which the catalyzed sol may be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of the pore structure and thermal insulation performance of an aerogel blanket produced accordingly are improved, the loss of raw materials is reduced through the impregnation process, the generation of process problems is reduced, and the generation of dust is reduced.

    摘要： A hydrophobic silica aerogel blanket according to the present invention has holes, so that the diffusion of a surface modifier is facilitated in a blanket during a surface modification process to improve the efficiency of surface modification. Accordingly, the hydrophobic silica aerogel blanket has not only excellent physical properties such as specific surface area and thermal conductivity, but also a controlled degree of hydrophobicity, and thus, may have high hydrophobicity.
