Comparison of Creep Behavior in Alumina Based Ceramics Densified by Spark Plasma Sintering and Hot Pressing
Spark plasma sintering (SPS) method, as plasma activated sintering, is a method applicable for rapid sintering of metals and ceramics. Owing to the advantage of rapid heating, the alumina ceramics obtained by SPS have a grain size and density comparable to those of hot pressed ones. The increase of densification rate may be related to some difference in ion transport characteristics. This study...
متن کاملEffect of Sintering Aid Composition on the Processing of Si3N4/BN Fibrous Monolithic Ceramics
Si3N4/BN fibrous monoliths were prepared with 4 wt% Y2O3 added as a sintering aid to the Si3N4. Residual carbon, present in the billet before hot-pressing, was shown to influence the final microstructure. The sintering aid glass, known to migrate into the BN cell boundaries during hotpressing, was not sufficient in quantity to prevent premature shear failure when samples were tested in flexure....
متن کاملSintering of Ceramics
Sintering with low frequency rf power (-50 M H z ) is a new technique with unique capabilities that has been used to sinter a variety of ceramic materials, including zirconia-toughened alumina, alumina, silicon carbide, and boron carbide. Processing with low frequencies offers many advantages compared to processing with conventional microwave frequencies (915 MHz and 2.45 GHz). Because of the l...

متن کاملOptimized Single-Mode Cavity for Ceramics Sintering
In this paper, we present a novel method of optimization of a single-mode cavity used for sintering ceramics. The goal of the optimization is to maximize the electric energy stored in the dielectric and minimize spatial variations of tashis field in the domain occupied by the material. Results of simulations of two configurations are discussed.
