Vv. Sinitsyn et al., THE EFFECT OF THERMAL-TREATMENT ON IRREVERSIBILITY OF SUPERPROTONIC PHASE-TRANSITION IN CS5H3(SEO4)(4)CENTER-DOT-XH(2)O CRYSTALS, Solid state ionics, 97(1-4), 1997, pp. 171-175
The effect of the thermal treatment on the superprotonic phase transit
ion (T-sp similar or equal to 348 K) and protonic transport of the Cs5
H3(SeO4)(4) . xH(2)O single crystals was studied. It was found that an
nealing at T > T-sp results in the suppression of the phase transition
to the low-conductivity state. This irreversibility of the superproto
nic phase transition is due to changes in the water content. A model o
f the water loss process is proposed.
