Abstract
The present invention concerns a process for the production of boron phosphide BP comprising the reduction of boron phosphate BPO4 with at least one alkaline earth metal (EA) according to Equation (1): BPO4+4 EA→BP+4 EA(O)(1).
Claims14
A process for the synthesis of boron phosphide (BP), said process comprising:
- the reduction of boron phosphate (BPO4) with at least one alkaline earth metal (EA) by mixing boron phosphate and the at least one alkaline earth metal, according to Equation (1):
- BPO4+4EA→BP+4EA(O) (1),
- wherein said process is a self-propagating high temperature synthesis, and
- wherein a part of a mixture comprising boron phosphate and the at least one alkaline earth metal is heated for initiating locally the reaction between boron phosphate and the at least one alkaline earth metal.
