Fabrication of SiC Nanoparticles by Physical Milling for Ink-Jet Printing

Abstract

Here we tried to show the possibility of mechanical milling method for fabrication of SiC nanoparticles and ink-jet printing method to make SIC patterns for use as several applications, e.g., micro hotplates. Planetary milling was employed to fabricate the nano-scale SIC particles from coarse powders. After 100 hours of milling, the size of the SiC particles decreased to about 100 nm, which was sufficient for the formulation of ink for ink-jet printing. The SIC particles were dispersed in an ink system consisted of ethylene glycol and ethanol with a small amount of additives. The ink with SiC nanoparticles could be successfully printed on an alumina substrate by the ink-jet printing method.
