Sintering of boron carbide and boron carbide-silicon carbide two-phase materials and their properties

Journal of Nuclear Materials, 1988
Boron carbide is a high-technological ceramic material (it is used for lightweight armor, neutron absorbers, wear pieces, etc.). Hot pressing (2200°C, 40 MPa, Ar atmosphere) and recently high isostatic pressing, are the best known ways for industrial preparation of boron carbide items.

Auger-electron spectra from boron carbide

Physical Review B, 1985
Auger electron spectroscopy (AES) has been used to study the surface composition and electronic structure of hot-pressed samples of boron carbide. The samples had bulk compositions of B/sub 9/C and B/sub 4/C. After removing oxygen and excess carbon contaminants from the surfaces of the samples by noble-ion sputtering the AES estimates of surface B/C ...

Boron Carbide Dust Flames

Combustion Science and Technology, 1972
Abstract The total burning time of boron carbide powder has been measured in premixed laminar boron carbide-propane-oxygen-nitrogen flames at atmospheric pressure. Burning times were several times longer than for elemental boron of the same particle size and were even longer than predicted by extrapolation from larger single-boron carbide particle ...

Boron Carbide-Silicon Carbide nanocomposites for next generation armour

2020
Modern warfare is developing rapidly; technology is becoming more advanced and the modern soldier requires more of it. With the increase in equipment there is an increase in weight which reduces mobility. Threats have also developed, in such environments greater protection can be required.

Degrader comprising boron carbide

2016
It is the objective of the present invention to provide a degrader that has excellent degrading capabilities with, for the same energy loss in the degrader, a lower emittance increase as currently used materials, without generating a strong neutron flux and without having severe toxic characteristics. This objective is achieved according to the present
