High Energy Planetary Ball Milling of SiC Powders

The effects of high-energy ball milling on SiC powders were studied using a planetary apparatus. Conditions to obtain nanostructured SiC powders with an average crystallite size of 4 nm were determined and powders were characterized by XRD, SEM and TEM analyses. This process was applied to prepare fine powders leading to dense SiC ceramics by sintering at 1900oC for 30 minutes

Al-SiC powder preparation for electronic packaging

Powders of pure aluminum (Al) with 55 and 75 vol.% SiC particles were ball milled in a conventional rotating ball mill with stainless steel and ZrO 2 balls for 1-10 h. The morphology and microstructure of the milled powders have been observed and analyzed by scanning electron microscopy (SEM) and energy dispersive x-ray (EDX). The milled powders were plasma sprayed onto a graphite substrate to

Mechanical Milling: a Top Down Approach for the Synthesis

Feb 03, 2012· It was found that the addition of nano size SiC greatly influenced the morphological characteristics of powder mixture, and also worked hardening of the powder to decrease the time taken to reach a steady state. Furthermore, Al became smaller crystallite size during ball milling of Al powder in the presence of SiC particles. 3.2.
