Effect of hydrostatic pressure on tlae ferroelectric )'>hase traxasition in KH2AS0. isstudied by dielectric naeasuremeuats. T]?e temperature at which tlae dielectric constantc( takes a peak value decreases witl? increasing pressure, and no peak is observed at15.0 kbar. Tlte anomaly of c. becomes broader witla pressure. T]?e transition tenapera-ture determined frorrn the peak of c. is well represented by tlae equationT(=B(p( -p)"' w']?ic]a is one of the nuanifestation of quantum ferroelectricity.Here, the critical pressttre PC is determixaed to be 14.8 kbar. Anotlter critical behaviorfor the quantum ferroelectricity near the critical pressure (z. - z: ) -' = DT" is exam-ined. It is found that c( at 14.5 kbar well represents this relationslaip.[KH.As0., ferroelectric, dielectric corxstant, quantum ferroelectricity, KDP, ll KDA, laigh pressurel
