Boron trichloride is a starting material for the production of elemental boron. It is also used in the refining of aluminium, magnesium, zinc, and copper alloys to remove nitrides, carbides, and oxides from molten metal. It has been used as a soldering flux for alloys of aluminium, iron, zinc, tungsten, and monel. Aluminium castings can be ...
Boron forms the complete series of trihalides, i.e. BX 3 (X = F, Cl, Br, I). The trifluoride is produced by treating borate salts with hydrogen fluoride, while the trichloride is produced by carbothermic reduction of boron oxides in the presence of chlorine gas: [49] [51] B 2 O 3 + 3 C + 6 Cl 2 → 2 BCl 3 + 3 CO
Unlike silicates, boron minerals never contain boron with coordination number greater than four. A typical motif is exemplified by the tetraborate anions of the common mineral borax , shown at left. The formal negative charge of the tetrahedral borate center is balanced by metal cations in the minerals, such as the sodium (Na + ) in borax . [ 1 ]
The modern synthesis involves dechlorination of boron trichloride using copper. [2] [better source needed]It can also be formed by the electrical discharge procedure of boron trichloride at low temperatures: [1] [3]
