“…In addition, there is also a growing demand for employing TM diborides in hightemperature electrodes [11][12][13], molten metal containment [1], refractory crucibles [14], thermocouple protection tubes in steel baths and aluminum reduction cells [15,16], reinforcement fibers [17,18], solar power [19][20][21][22][23], and armor applications [16]. The use of diborides in advanced nuclear fission reactors as neutron absorber materials, which are intentionally introduced into reactor cores to control the neutron balance, is also of great interest [15,24,25].

“…C [1,[4][5][6][7][8][9] and a diagram including low-temperature phases (i.e., boron rich boron carbides) [6]. Due to its attractive properties, it can be used in many advanced industries, which may include nuclear power, military industry, or medicine [1,4,5,[10][11][12][13][14][15][16][17]. A number of distinguishing properties of boron carbide include very high hardness (~30 GPa), low density (2.52 g/cm 3 ), high melting point (carbide with a B 13 C 2 formula melts congruently at about 2450 • C), high Young's modulus (about 450 GPa), chemical inertness, and also high neutron capture cross section (600-700 barn) [1,4,5,18].…”

Effect of Expanded Graphite on the Reaction Sintering of Boron Carbide

This paper presents novel results of research focused on reaction sintering of a mixture of expanded graphite and amorphous boron. It has been shown that as a result of combining the synthesis from the elements with sintering under pressure, dense boron carbide polycrystals (95% TD) can be obtained in which stable structures dominate, i.e., boron carbides of stoichiometry B13C2 and B4C. Sintering was carried out on boron excess systems, and reaction mixtures with the following mass ratios (B:C = 5:1; 10:1; and 15:1) were used. Boron excess systems were used due to the presence of additional carbon during sintering since the matrix, reactor lining, and heating elements were made of graphite. 1850 °C was considered to be the optimum reaction sintering temperature for all of the systems tested. This shows that a reduction in the sintering temperature of 200–300 °C was observed with respect to traditional sintering techniques. Micro-cracks are present in the sinters, the presence of which is most likely due to the difficulty in removing the gaseous products which accompany the boron carbide synthesis reaction. The elimination of these defects of sintering requires further research.

“…For example, the neutron absorption cross-section of 10 B is 3840 barn and that of 11 B is essentially zero (50.01 barn) for thermal neutrons [1,2]. For fast neutrons with energy E^0.1 MeV, the neutron absorption cross-section of 10 B becomes about 1 barn and that of 11 B is negligibly small.…”

This article describes the method for measuring the isotopic abundance of 10 B in nuclear grade boron carbide using inductively coupled plasma-quadrupole mass spectrometry (ICP-QMS). The results of investigation revealed that both the integration time and the dwell time have a major influence on the reproducibility of ICP-QMS measurements. As a result of optimization of the measurement conditions, reproducibility below 0.2% relative standard deviation (RSD) (0.17% RSD maximum) was achieved. In addition, the measured value of the isotopic abundance of 10 B for each sample well agreed with the values measured by the TIMS. Thus, the method described in the present investigation was very effective in the analysis of isotopic abundance of 10 B in B 4 C or H 3 BO 3 . The results of this study suggest that ICP-QMS could be applied to the precise analysis of the isotopic abundance of 10 B required in the field of nuclear applications.
