TL;DR
This paper investigates the hardness of boron (III) oxide in different phases, revealing that high-pressure B2O3 has a hardness comparable to tungsten carbide, significantly higher than its glass-like form.
Contribution
The study provides the first comparative hardness measurements of glass-like and high-pressure phases of B2O3, highlighting the substantial increase under pressure.
Findings
Glass-like B2O3 has a hardness of about 1.5 GPa.
High-pressure B2O3 has a hardness of approximately 16 GPa.
High-pressure B2O3's hardness is comparable to WC-10% Co alloy.
Abstract
Our findings show that the hardness of glass-like B2O3 is of about 1.5 GPa, while the hardness of the high-pressure phase is higher by a factor of 10 (16(5) GPa) and comparable with the hardness (16 GPa) of the WC-10% Co hard alloy.
