摘要：
A two-step process (milling and then heat treatment) was used for the preparation of alpha-Si3N4 nano powder. The influence of the milling time and heat treatment temperature as processing parameters were investigated on the formation of alpha-Si3N4. Silicon nitride ceramic was produced by spark plasma sintering at 1700 degrees C for 15 min, using MgSiN4 additive. The optimum sample was produced in a 30 h milling time, heat treatment at 1300 degrees C, and a 22 degrees C/min heating rate conditions. X-ray fluorescence analysis showed that the purity of the final product is above 98%. Nanoindentation hardness and Young's modulus of the SPS-ed sample were measured as 17 2.0 GPa and 290 +/- 11.0 GPa, respectively. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
