1. A method of compacting aerogel particles, comprising feeding aerogel particles into a molding apparatus and molding the aerogel particles in the molding apparatus, wherein the aerogel particles are degassed prior to and/or during molding. 2. The method of claim 1, wherein additives, fillers, and/or binders are added to aerogel particles. 3. A method according to claim 2, characterised in that the components are in particulate or fibre form. 4. A method according to claim 2, characterised in that the components are liquid or pasty. 5. A method according to claim 1, characterised in that the starting material is subjected to a negative pressure. 6. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into granules in the molding apparatus, wherein the granules are sorted according to their size. 7. The method of claim 6, wherein the granules which are below the desired granular range, are returned to the molding apparatus. 8. The method of claim 6, wherein the granules which are above the desired granular range, are comminuted. 9. The method of claim 6, wherein the granules are dried prior to further processing. 10. The method of claim 1, wherein the aerogel particles are molded into a scab. 11. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into a scab, wherein the scab is dried prior to further processing. 12. The method of claim 6, wherein a male die molds the aerogel particles in a female die. 13. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into granules in the molding apparatus, wherein the aerogel particles are molded between a roller and a female die. 14. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into granules in the molding apparatus, wherein the molding apparatus comprises a perforated female die and moldings that are cut off on an output side of the molding apparatus. 15. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into granules in the molding apparatus, wherein the aerogel particles are molded between two rollers. 16. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus having an output side and molding the aerogel particles into granules in the molding apparatus, wherein the aerogel particles are molded between two rollers, at least one of which is a perforated hollow roller, the moldings being cut off on the output side. 17. A method of compacting aerogel particles, comprising feeding the aerogel particles into a molding apparatus and molding the aerogel particles into granules in the molding apparatus, wherein the aerogel particles are molded between two rollers, at least one of which is profiled. 18. A method of compacting aerogel particles, comprising the steps of: feeding a starting material comprising aerogel particles into a molding apparatus; compressing the aerogel particles into larger aerogel particles; and separating smaller aerogel particles from the larger aerogel particles. 19. A method of compacting aerogel particles, wherein the aerogel particles are reacted with a silating agent and are fed into and molded in a molding apparatus. 20. A method of compacting an aerogel, comprising: forming gel particles, reacting the gel particles with a silylating agent, drying the gel particles to produce aerogel particles, and feeding the aerogel particles into a molding apparatus and molding the aerogel particles.
