Phase equilibria and crystal structure of compounds of the Tb–B–C system at 1270 K

Abstract: Методами рентгенофазового і рентгеноструктурного аналізів енергодисперсійної та рентгенівської спектроскопії за довжиною хвилі (WDXS) побудовано ізотермічний переріз діаграми стану системи Tb-B-C при 1 270 K. Підтверджено існування восьми тернарних сполук. Визначено склади нових сполук ~Tb2BC3, ~Tb4B5C18 та область гомогенності фази Tb5(B,C)x, що належить до структурного типу La5B2C6 й описано формулою Tb5(B,C)x, 8,3 x 9,2: a = 8,102(1), c = 11,568(2) Å (для Tb5B2,1C6,2) та a = 8,054(1), c = 12,335(4) Å (для… Show more

“…The interaction of components in the binary Tb-C system at 800 °C was studied earlier and crystal structure parameters of the binary terbium carbides were presented in Refs. [4,8]. According to the phase diagram of the Fe-C system [9], which includes a review of the results of both, experimental and theoretically calculated phase equilibria, no thermodynamically stable phase occurs at 800 °C.…”
