    • The present invention pertains to a method for encapsulating a liquid or pasty substance in a cross-linked encapsulation material, characterized in that the liquid or pasty substance and an inorganic at least partially condensed and organic polymerizable inorganic-organic hybrid material are co-extruded as a cross-linkable precursor material of the encapsulation material through a nozzle, such that the cross-linkable precursor material surrounds the liquid or pasty substance, whereupon the co-extruded material is passed through a zone, in which a cross-linking of the precursor material is brought about. In preferred embodiments, the precursor material for the encapsulation material may be produced from or using silanes of the formula (I) RaR1bSiX4-a-b  (I) by means of hydrolytic condensation, wherein the substituents R, R1 and X may each be the same or different and wherein R represents an organic radical that is bound to silicon via carbon and that can be cross-linked by heat or actinic radiation, R1 represents a radical that is bound to silicon via carbon and that cannot be organically cross-linked, X is a group that can be hydrolyzed under hydrolysis conditions or that can be separated from the silicon, or is OH, a is 1 or 2, b is 0 or 1, and a+b may be 1 or 2. Inorganic hollow spheres or hollow fibers can optionally be produced by burning the organic components of the capsules or fibers obtained in this manner and evaporating the content.
