Here, we report the synthesis of rhombohedral Cr 2 S 3 (rh-Cr 2 S 3) via a high-temperature reaction, which was milled and subsequently sintered using high-pressure FAST (HP-FAST). Although the sintering temperature was varied between 973 and 1223 K, the remaining sintering parameters were kept constant.

The sintering behavior and mechanical properties of cubic boron nitride (cBN) composites, using the mixture of cBN–Ti 3 Al and cBN–Ti 3 Al-Al as the starting material respectively, were investigated under high pressure and high temperature (HPHT) conditions. The results show that the samples of cBN–Ti 3 Al-Al sintering system have more homogeneous microstructures.

Abstract: The high pressure and high temperature sintering of α-Si 3 N 4 and γ-Si 3 N 4 with Y 2 O 3-Al 2 O 3-La 2 O 3 as additives were studied under pressures of 5.4 GPa and temperatures of 1420-1770 K. The effects of sintering temperatures and pressures on properties of sintered ceramic samples were investigated with X-ray diffraction and scanning electron microscopy.

Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles pressed together in the compact.

The pressure-assisted sintering approaches differ in stress state during densification. This influences particle sliding and dimensional change. The mean pressure, or hydrostatic stress, determines pore shrinkage and controls the densification rate. Shear induces particle rearrangement by sliding, collapsing large pores while disrupting particle surface films.
