Self-Combustion Synthesis of AlN-SiC Solid Solution Powder in Air with Assistance of High-Energy Mechanical Milling

Abstract

A very simple synthesis method of AlN-SiC solid solution powder, i.e. self-combustion of Al, Si3N4 and C mixture in the air only with assistance of high-energy mechanical milling, was proposed in the present work. The effect of compositions on the combustion behavior and the product was studied and the results showed that the amount of Al in the starting powder was the key factor affecting the combustion behavior, the phase assemblages and the morphology of products.
