The present invention relates to the use of aerogels as carrier materials for active substances in agriculture and/or veterinary medicine.

Use of aerogels in agriculture

The present invention relates to novel, organically modified aerogels, uses thereof, and a process for producing them in which a) a hydrogel is introduced as an initial charge, b) the hydrogel obtained in step a) is subjected to surface modification, and c) the surface-modified gel obtained in step b) is dried. The present invention additionally relates to novel, organically modified wet gels, to a process for producing them, and to their use.

Organically modified aerogels, processes for their preparation by surface modification of the aqueous gel, without prior solvent exchange, and subsequent drying, and their use

Multilayer composite materials with at least one aerogel-containing layer and at least one other layer, a process for producing the same and their use are disclosed. The aerogel-containing layer(s) further contain at least one binder.

A method of producing substantially spherical lyogels in water insoluble silylating agents is provided. The present invention refers to a method of producing substantially spherical lyogels in which a) a lyosol is provided, b) the lyosol obtained in step a) is transferred to at least one silylating agent in which the lyosol is insoluble, and c) the spherical lyosol formed in step b) is gelatinised in at least one silylating agent in which the lyosol is likewise insoluble, to produce the lyogel.

Method for the production of a silica glass crucible with crystalline regions from a porous silica glass green body

Extremely high solids content silica dispersions are useful for forming green bodies of near net shape as compared to the shape of the bodies after sintering. The green bodies are particularly useful for sintering to form low impurity-containing crucibles for single crystal silicon production.

High-solids SiO2 dispersions, process for producing them, and their use

Aerogel particles, in particular in the form of composite materials, are used to deaden structure-borne and/or impact sounds.

Use of aerogels for deadening structure-borne and/or impact sounds

The present invention refers to a method of producing organically modified aerogels on a basis of silicon tetrachloride in which: a) a hydrogel is obtained by direct reaction of silicon tetrachloride with water, b) the hydrogel obtained in step a) is surface-modified, and c) the surface-modified gel obtained in step b) is dried.

Method of producing silicon tetrachloride-based and organically modified aerogels

Process for preparation of hydrophilic or partially hydrophilic inorganic aerogels. The invention relates to a process for the preparation of hydrophilic or partially hydrophilic inorganic aerogels, which comprises pyrolyzing a hydrophobic inorganic aerogel in the presence of oxygen at temperatures in the range from 100 to 1000&deg; C.

Process for preparation of hydrophilic or partially hydrophilic inorganic aerogels

The invention concerns a coated sheet which includes an aerogel layer, a method of manufacturing the coated sheet and its use.

Aerogel-coated sheet

The invention relates to the use of inorganic aerogels as an auxiliary and/or excipient for pharmaceutical active compounds and/or preparations.

Use of inorganic aerogels in pharmacy

Process for preparing organically modified aerogels in which the salts formed are precipitated out

The invention relates to a process for preparing organofunctionally modified aerogels by gelling a water glass by means of polycondensation and then converting it, by drying while retaining the structure of the gel, to give an aerogel, which process comprises reacting the gel, before drying, with an at least bifunctional organic compound, at least one functional group serving as a bond to the aerogel, while the remainder are retained, to aerogels which are obtainable by the novel process, and to their use.
