Definitions
- Silicon compounds e.g. Tetraethyl orthosilicate or alkylated titanium compounds, e.g. Tetraisopropylorthotitanate be used.
- the liquid precursor-solvent solution evaporates, resulting in the formation of nanoparticles due to the high temperature in the stabilized flame.
- the nanoparticles produced are quenched using suitable techniques (e.g., quenching), collected, and discharged from the manufacturing process.
- the present process allows the preparation of the nanoparticles, in amounts above a few grams per hour (and thus above the laboratory scale).
- the nanoparticles produced have a particle diameter with a d95 value of less than 1000 nm, preferably of less than 800 nm, particularly preferably of less than 500 nm.
- the value d95 of e.g. 10,000 nanometers, that 95% of the particles of a population have a diameter of less than 1000 nm.
- the nanoparticles produced by the present process can be used in a variety of ways. Depending on their properties (such as transparent, electrically conductive, electrically insulating, thermally conductive, or catalytically active), the nanoparticles can be used as a coating material, in electrical appliances, for heat conduction or thermal insulation or as a catalyst, etc.
