Boron: Elementary Challenge for Experimenters and Theoreticians

“…[9] Moissans samples were contaminated (but not as badly as those of the discoverers of boron: von Crell, Gay-Lussac and Thenard, and Davy [10][11][12] ), and one of the contaminating substances was magnesium diboride. MgB 2 is thus a well-known binary compound, but it is only since 2001 that we have known it becomes a superconductor at 39 K. [13] It has since become possible to produce it on an industrial scale in the form of Many of the fundamental questions regarding the solid-state chemistry of boron are still unsolved, more than 200 years after its discovery.…”

Bor – elementare Herausforderung für Experimentatoren und Theoretiker

“…[9] Die Moissanschen Proben waren verunreinigt (wenn auch nicht so stark wie die der Entdecker von Bor, von Crell, Gay-Lussac und Thenard bzw. Davy [10][11][12] ), und bei einer der Verunreinigungen in diesen Proben handelte es sich um Magnesiumdiborid.…”

“…Weiterhin kennt man (röntgen)amorphes Bor, die Form von Bor, die Moissan 1895 in Händen hielt, als er Dibortrioxid mit Magnesium reduzierte. [9] Die Moissanschen Proben waren verunreinigt (wenn auch nicht so stark wie die der Entdecker von Bor, von Crell, Gay-Lussac und Thenard bzw. Davy [10][11][12] ), und bei einer der Verunreinigungen in diesen Proben handelte es sich um Magnesiumdiborid.…”

A Historical Perspective on Research Related to Ultra‐High Temperature Ceramics

“…† Even though Acheson was the first to report a commercially viable synthesis process for SiC [31], Moissan's research on SiC [32], as well as the carbides of Mo [33], Ti [34], and Zr [35] was notable because of its breadth and depth. After the initial reports, scientific publications on borides and many of the carbides were sporadic, but progress was made in areas such as bonding [36], electrical properties [37], and electronic structure [38] through the first half of the 1900s.…”
