The electrical conductivity of the cold sintered salt KH2AsO4 has been investigated within temperature range from room temperature to about 500°C during multiple heating and cooling cycles. The reversibility of the dehydration process KH2AsO4 ⇄ β-KAsO3 has been established. The electrical characteristics were correlated with thermal and structural transformations. The unit cell dimensions of the β-KAsO3 phase were determined: ao= 14.092(5) Å, bo= 13.099(4) Å, Co = 8.891(2) Å, βo = 96.37(2)o and Vo = 1631(1) Å3.
