| The Direct Nanoparticle Deposition process is based on combustion of gaseous and atomised liquid raw materials in an atmospheric oxy-hydrogen flame. The method produces nanosize metal oxides, noble metals and their combinations. Raw materials with very different vapour pressures can be used. Efficient mixing of materials ensures homogeneous multicomponent-nanoparticle composition. Rapid quenching and a short residence time produce monodisperse particles. The DND process is currently in industrial use in the production of ultrapure, doped optical fibres and in glass colouring. Due to the versatility of the method it can be used in various applications where multicomponent materials with well scalable production is required. |
