Sputter deposition of high resistivity boron carbide [PDF]

open access: yes, 1998
We have succeeded in the rf magnetron sputter deposition of high resistivity boron carbide (B1−xCx). This has been accomplished by the sputter depositing the boron carbide from a methane saturated boron carbide target.

Steam oxidation of boron carbide-stainless steel liquid mixtures

open access: yes, 2012
International audienceIn the framework of nuclear reactor core meltdown accidents studies, the oxidation kinetics of boron carbide-stainless steel liquid mixtures exposed to argon/steam atmospheres was investigated at temperatures up to 1527°C. A B-Cr-Si-

Study of laser-produced plasmas from boron, carbon and boron-carbide targets [PDF]

open access: yes, 2001
Spectroscopic investigations were made on plasma clouds created by 20 ns, 3 J ruby laser pulses impinging perpendicularly onto targets of boron carbide, carbon and boron. The irradiance on the targets was about 132 GW cm^-2.

Processing of complex-shaped collimators made via binder jet additive manufacturing of B4C and pressureless melt infiltration of Al

open access: yesMaterials & Design, 2019
Complex collimator geometries are desired for custom neutron scattering applications. Boron carbide (B4C) is a suitable candidate collimator material because its high boron content results in a large neutron-absorbing cross section and it can be safely ...

Synthesis, Densification and Characterization of Boron Carbide

open access: yes, 2013
This paper presents the experimental results on synthesis of boron carbide from its elements. Boron to carbon ratio of 4:1 and a synthesis temperature of 1850°C was found optimum to obtain stoichiometric B4C.

Method for Removing Impurities by Treating Silicon Tetrachloride with Hydrogen Plasma

open access: yesInorganics
The transformation of organochlorine and organic impurities such as CCl4, C2H2Cl2, C2HCl3, C2Cl4, C2H2Cl4, CH4, C3H8, C4H10, and C6H6 in the content range of 10−2–10−6 wt.%, as well as BCl3 impurities at the level of 3 × 10−2 wt.%, was considered.

The Friction of Boron Carbide in Controlled Atmospheres

open access: yes, 1973
Experiments on the sliding of boron carbide on boron carbide in atmospheres of dry air and water vapor at room temperature have shown the frictional behavior of boron carbide to be similar to that of graphite.

Performance enhancement for thermal conductivity and thermal energy storage of sludge-incinerated slag/KNO3 phase change composites

open access: yesReli fadian
The industrial production and urban residents' lives have led to a large amount of wastewater and sludge, and the landfilling of sludge has caused severe ecological damage.

Role of boron carbide in carbothermic formation of hexagonal boron nitride

open access: yes, 2006
Formation of hexagonal boron nitride by carbothermic reduction of boric oxide under nitrogen atmosphere at 1500 degrees C was investigated. Experiments were performed for durations in the range of 15 min to 3 h. Reaction products were subjected to powder
