PROCESS FOR THE MANUFACTURE OF NANO-SIZED POWDERS |
摘要 |
<p>Nano-sized metal-bearing powders and doped-powders are synthesized by means of a process whereby a non-volatile metal-bearing precursor powder or powder mixture is dispersed in a hot gas stream at relatively low temperatures. A first volatile reactant is added, converting the metal in the precursor into a volatile metal compound. Subsequently a second volatile reactant is injected into the gas stream, converting the volatile metal compound into a solid, which condenses as a nano-sized metal-bearing powder upon quenching. Finally, the vapour/metal-bearing powder mixture is separated from the gas stream.</p> |
