The effects of an electric field on phase separation in CBP (CaOB2O3P2O5) h
ave been studied. It was discovered that an electric field can inhibit the
process of phase separation in CBP glasses. If the electric field strength
is increased, the inhibiting effect will increase, too. The mechanism of ph
ase separation in an electric field has been discussed in light of the ir s
pectrum of CBP glasses.
