六ホウ化バリウム 化學(xué)特性,用途語(yǔ),生産方法
化學(xué)的特性
metallic black cub; -100 mesh 99.5% purity [CER91] [CRC10]
使用
Barium hexaboride has been considered as a candidate
for manufacture of a “hot-cathode” electron gun
for use in various instruments.
製造方法
Barium boride can be formed directly from the
elements. Ba melts at 727 °C and boron melts at
2076 °C. Therefore, if a vapor of Ba metal at >750 °C
(red-heat) is passed over crystals of boron, a chemical
reaction forms the desired boride. However, to obtain
stoichiometric compositions, it is better to heat the
well-mixed powders of Ba and B to obtain specific
compounds:
Ba + 6B→BaB
