    Abstract: The present invention relates to a method for producing a silica aerogel and a silica aerogel produced thereby. More specifically, a first water glass solution is used to form a first silica wet gel, and then a second water glass solution is additionally added to form a second silica wet gel organically bonded to the first silica wet gel which serves as a basic skeleton, so that a silica aerogel with enhanced physical properties is formed to increase the resistance to shrinkage in ambient drying. Thus, a low-density silica aerogel may be formed, and the concentrations of the first and second water glass solutions may be adjusted to control the physical properties of the silica aerogel.

    Abstract: Provided is a method for producing hydrophobic silica aerogel granules and hydrophobic silica aerogel granules produced thereby, the hydrophobic silica aerogel granules having a suppressed level of specific surface area deterioration and scattering properties. In the method for producing the hydrophobic silica aerogel granules, surface modification, gelation, and solvent substitution can be simultaneously performed in one step, thereby decreasing production time and increasing productivity. Also, by adjusting the addition amount of a non-polar organic solvent when proceeding with a reaction, hydrophobic silica aerogel granules with suppressed scattering properties can be produced. In addition, the hydrophobic silica aerogel granules are silica aerogel particles induced to agglomerate with each other through physical bonding, so that there is an advantage in that the granules can be easily changed into a powder form, thereby having excellent industrial applicability.

    Abstract: The present invention relates to a method of preparing a high hydrophobic silica aerogel having a high specific surface area and a low tap density, and a hydrophobic silica aerogel prepared thereby. The method of preparing a hydrophobic silica aerogel according to the present invention may have good productivity and economic efficiency, because preparation time is reduced by simultaneously performing surface modification, gelation, and solvent substitution in a single step, and may control a degree of hydrophobicity of the prepared silica aerogel by controlling a surface modification reaction by including a step of adding ammonium hydroxide. Thus, the preparation method according to the present invention and the hydrophobic silica aerogel are suitable for industries that need the method and the hydrophobic silica aerogel, particularly, industries that need a silica aerogel having high hydrophobicity or industries that need a silica aerogel having various degrees of hydrophobicity.
