摘要: The existence of a high temperature phase transition in KD2PO4 was confirmed by thermal analysis, dielectric analysis and Raman spectroscopy. results showed that presented only one at about Ttr = 430 K, which is much lower than the decomposition temperature. absence shift attributable to dehydration product indicated HTPT had nothing do with decomposition. structural change during discussed. strong similarity between HT-phase tetragonal decreases crystal. hydrogen–deuterium exchange can be suppressed under protective ambient environment, helps improve annealing A new method developed using silicone oil as environment higher up 403 thus improving quality crystals.
