Manufacture and form
CaB6 is produced in an arc melting process from CaO und B₂O₃ via carbothermic reduction.
CaO + B₂O₃ + 5 C → CaB₆ + 5 CO₂
The large blocks produced at the same time are reduced by means of a number of grinding stages to a powder with defined particle size. Depending on its further use, the material is ground until in the micron range.
