摘要： An object of the present invention is to provide a novel aerogel including a drying method, the aerogel having a larger size, good productivity such as high yield, and high transparency; and a method for producing the aerogel. The object of the present invention has been achieved with the following: An aerogel having: a silsesquioxane structure, the aerogel exhibiting two exothermic peaks observed in a temperature range of 300 to 600°C as measured by TG-DTA (thermogravimetry-differential thermal analysis) under an inert gas atmosphere containing 80% by volume of an inert gas and 20% by volume of oxygen. A method for producing an aerogel including: a drying step including at least: a first step in which an aerogel which has undergone condensation of a hydrolysate is placed in a liquid phase system having a first liquid phase and a second liquid phase; a second step in which a first solvent constituting the first liquid phase is evaporated from the first liquid phase at a temperature greater than room temperature; and a third step in which heating is still continued after the first liquid phase is evaporated off, the first solvent having a specific gravity and a boiling point lower than those of a second solvent constituting the second liquid phase, and an affinity for the aerogel.

摘要： The invention relates to a porous silica with a median pore diameter of 210 Å to 500 Å, and with a pore volume of 0.80 cm 3 g -1 to 1.2 cm 3 g -1 . The invention also relates to a method of producing a porous silica, in which a liquid phase-dispersed nanoparticulate silica is gelled in the presence of either (i) a Bronsted acid and an amine compound having two or more primary or secondary amine groups or (ii) an amino acid.
The invention further relates to the use of the porous silica as a stationary phase for separation, and also to a separation column or vessel containing the porous silica.

摘要： A low-density gel product of the present disclosure has a coating layer on a surface thereof, the coating layer being composed of a polymer of a gas-phase polymerizable monomer. The low-density gel product of the present disclosure has an improved mechanical strength. The low-density gel product is, for example, an aerogel or xerogel. The low-density gel product can be, for example, in the form of a monolithic body such as a sheet or in the form of particles. The gas-phase polymerizable monomer is, for example, at least one selected from an olefin, styrene, a styrene derivative, (meth)acrylic acid, a (meth)acrylic acid ester, para-xylylene, and a para-xylylene derivative.

摘要： A method for preparing a sol-gel derived SiO2 having a very fast bioresorption rate where a sol-gel derived SiO2 is prepared from a sol comprising water, an alkoxide or inorganic silicate and a lower alcohol using a mineral acid or a base as a catalyst and the sol is aged and dried. The method uses a pH from 1.5 to 2.5, a molar ratio of water to the alkoxide or inorganic silicate of 0.5 to 2.5, a molar ratio of alcohol to the alkoxide or inorganic silicate is ≥0.5; and the sol is either let to gel without induced changes of composition and without forced drying of the sol, or a change of composition is induced; and within a time of ≤30 minutes, from the induced change forced drying of the sol is carried out or initiated.

摘要： It is an object of the invention to provide a rapid and economically viable process which is notable for efficient use of material, especially of the silylating agent, and by means of which organically modified lyo- or aerogels are obtained in a rapid and simple manner. This object is achieved by virtue of the invention providing a process for producing organically modified gels selected from lyo- and aerogels by (i) emulsifying a basic polar phase comprising water and starting materials for silicatic gels in a nonpolar phase containing a water-immiscible precursor for an active silylating agent, (ii) starting formation of gel and ageing by lowering the pH, and then (iii) starting the silylation and the exchange of solvent by lowering the pH. If the gels are aerogels, the gels provided can be used for thermal and/or acoustic insulation.
