— Pure B6O powder and B6O powders admixed with 1.5 wt% of MgO, 1.4 wt% of CaO, and 0.7 wt% of CaCO3, were sintered and the microstructure, phase composition and mechanical properties were investigated. Pure B6O powders were sintered at a temperature of 1900 o C and a load of 50 MPa for 20 minutes in an argon environment, while the B6O-admixed powders were sintered at a temperature of 1850 o C and loads from 50-80 MPa, under the same environment. The addition of the alkaline earth metal oxide…

High pressure consolidation of B6O-diamond mixtures
Sintered composites in the B6O-xdiamond (x= 0–80 vol%) system were prepared under high pressure and high temperature conditions (3–5 GPa, 1400–1800°C) from the mixture of in-laboratory synthesized
Boron suboxide materials with rare-earth metal oxide additives
The basis of this study is that the mechanical properties of Boron suboxide (B6O) materials, especially fracture toughness are greatly influenced by the composition of the grain boundary phase and
Synthesis of aluminum infiltrated boron suboxide drag cutters and drill bits
Synthesis of boron suboxide (B6O) was made by reactive sintering of crystalline boron and zinc oxide powders at 1450 °C, in argon, for 12 h. After sintering, Vickers microhardness testing was
B6O: A Correlation Between Mechanical Properties and Microstructure Evolution upon Al2O3 Addition During Hot Pressing
B6O powders were hot pressed with and without Al2O3 as a sintering additive at temperatures up to 1900°C and a pressure of 50 MPa. The microstructure of a doped and undoped sample was studied by

Boron suboxide: As hard as cubic boron nitride
The Vickers hardness of boron suboxide single crystals was measured using a diamond indentation method. Under a loading force of 0.98 N, our test gave an average Vickers hardness of 45 GPa. The
