Pure MgAl2O4 powder can be hot-pressed to transparency in the presence of LiF (1-3.5 %; best ~1 %), at relatively low pressure(50 MPa or less), if peak temperatures around 1650 °C are used. At the concentration levels and conditions present during h

Ti(C,N) and Ta powders were mechanically alloyed to synthesize the (Ti,Ta)-carbonitride solid solution. As a result of milling, nanocrystalline Ti(C,N) was obtained. Mechanical alloying greatly improves the sinterability of the Ti(C,N)–Ta powders,

B6O is a possible candidate of superhard materials with a hardness of 45 GPa measured on single crystals. Up to now, densification of these materials was only possible at high pressure. However, recently it was found that different oxides can be util
