摘要: Abstract The effect of deuteration on ferroelastic-ferroelastic phase transitions and ferroelastic domain structure in (NH4)3H(SeO4)? was investigated. Crystals various degrees were studied. temperature width triclinic found to decrease with increasing degree deuteration. superionic (2) - (1) transition lowered from 306 K for the non-deuterated crystal 293 highest Additional result a change pattern phase.
