Calcium perborate has been used as an oxidizing and
teeth-whitening agent in dentistry and in some applications
in polyolefin polymer preparation.

Calcium perborate, CaB
2O
6, has the CAS number of
54630-47-6. Its Lewis formula is shown in Fig. 6.23.
It has been prepared by the reaction:
CaCl
2 (aq) + Na
2B
4O
5 +H
2O
2→Ca(BO
3)
2·2H
2O
+ 2NaCl
This mixture was stirred, and the temperature was
maintained at 20-25 °C. The solids were then filtered
out, and the filter cake was reslurried with water and
filtered again. Finally, the solids were dried overnight
in a vacuum oven at 50 °C. The product thus obtained
was a calcium perborate, Ca(BO
3)
2, containing the
equivalent of 27.9% calcium oxide [CaO] and 10.0%
active oxygen [O].
