What is BARIUM HEXABORIDE?
Chemical properties
metallic black cub; -100 mesh 99.5% purity [CER91] [CRC10]
The Uses of BARIUM HEXABORIDE
Barium hexaboride has been considered as a candidate for manufacture of a “hot-cathode” electron gun for use in various instruments.
Preparation
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→BaB6
