A process for the production of a molding made of high-purity transparent quartz glass, comprising the following steps: (a) providing a composition for the production of a molding made of high-purity transparent quartz glass in a device, the composition comprising the following components: at least one polymerizable organic binder which has been dissolved in an organic solvent; a polymerization initiator or crosslinking agent, respectively, which, via supply of light or heat, initiates the polymerization or crosslinking of the at least one polymerizable organic binder; and at least one type of spherical quartz glass particles, which are present in dispersed form in the at least one polymerizable organic binder and have a diameter in the range from 7 to 100 nm; (b) incompletely hardening the at least one polymerizable organic binder contained in the composition via spatially restricted supply of light or heat, whereby a green part is obtained as primary structure; (c) separating the non-hardened at least one polymerizable organic binder, inclusive of the components contained therein, from the primary structure; and optionally at least once repeating the steps (a), (b) and (c); (d) optionally post-treating the primary structure by at least one process selected from the group consisting of structuring by means of a forming tool, irradiating with high-energy radiation and subsequent developing, milling, drilling, laminating, bonding, grinding, polishing, lapping, engraving and treating with heat or laser light; (e) removing a non-hardenable component potentially present in the primary structure; (f) debinding the primary structure by thermal treatment, whereby a brown part is obtained as porous secondary structure; (g) optionally filling up the porous secondary structure with at least one filler; and (h) sintering the porous secondary structure, whereby the final molding is obtained.
