Application

  • Calcium metaborate can be used as an additive to improve the performance of nickel-metal hydride batteries.
  • It is used as a precursor to synthesize calcium hexaboride (CaB6) by electro-reduction that can be used as high capacity anode for aqueous primary batteries.
  • It can also be employed in the preparation of calcium-doped borate glass for thermoluminescent dosimeters (TLD).
