High-pressure synthesis of superconducting Nb{1-x}B2 (x = 0-0.48) with the maximum Tc = 9.2 K [PDF]
, 2002 Superconductivity with Tc above 9 K was found in metal-deficient NbB2 prepared under 5 GPa, while no clear superconductivity was observed down to 3 K in stoichiometric NbB2. The superconductivity was observed above x = 0.04 in Nb1-xB2.

High pressure assisted WC/Co hardmetal sintering–effect of sintering temperature [PDF]
AIP Conference Proceedings, 2017 WC/Co is widely used as cutting tools, because has a unique combination of high strength, hardness, toughness, and moderate stiffness, especially with fine grained WC and finely distributed cobalt. WC/Co powder mixture sinters by different methods such as vacuum sintering, microwave sintering and SPS.

High pressure Sintering of TiB2 powder with Less Sinterability.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1993 A compact of TiB2 was fabricated by sintering powder TiB2 with less sinterability by use of a high pressure technique. Densification of the sintered compact was made at a pressure of 5.4 GPa and temperatures up to 1600°C for 5 hours. The sinterability was estimated from mechanical and electrical properties.

High pressure sintered ZrO2-6%wt REO
Science of Sintering, 2007 The sintering conditions employed in this work are innovative, due to the use of an alternative technology to process ZrO2-REO (rare earth oxide mixture), so called high temperature - high pressure (HPHT). A pressure of 5GPa was used, temperatures of 1100, 1200, and 1300 o C, for times of 2 and 5 minutes.
