Synthesis and characterization of Al, Y, Co and Cr substituted ultrafine powder of NiFe2O4
(Materials Science Forum, 2004)
The ultrafine spinel NiFe1.9M0.1O4 powders (M=Al, Y, Cr, Fe) were synthesized by thermal decomposition of appropriate mixtures of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)(x)]) at 500 degreesC. ...
Critical parameters of Si conversion into Si3N4 nanophase powder for plasma process
(Materials Science Forum, 1998)
Paper presents the results of plasma synthesis of Si3N4 nanophase powder in a DC nitrogen thermal plasma. Silicon powder (particle diameter range 0.1 divided by 60 mu m, mean mass particle diameter 13.6 mu m, specific ...
Thermal plasma synthesis of ultrafine Si3N4 and SiC ceramic powders
(Materials Science Forum, 1996)
Thermal plasma processes for ultrafine ceramic powders synthesis are discussed and explained by examples of Si3N4 and SiC powder synthesis routes, consisting of silicon powder evaporation in nitrogen plasma, followed by ...
