Synthesis of Coated Nanoparticulate Ceramic Powders

摘要

The microwave plasma process is capable to produce larger quantities of nanoparticulate powders with mean particle sizes in the range from 5 to 20 nm. The products may be oxides, nitrides, sulphides, selenides, or even metals. additional, it is possible to coat these particles with a layer of a second ceramic, a polymer or carbon. Sintered ZrO_2-Al_2O_3 nanocomposites and superparamagnetic cores of #lambda#-Fe_2O_3-polymer composites are given as examples
