摘要
Experimental data on potassium titanyl phosphate KTiOPO4 (KTP) morphology have been compared with theoretical models, based on layer thickness dhkl, on the attachment energy Eatt of the F-faces of KTP and on a computer model, which calculates the roughening temperature TR of a crystal face from its connected net. Seven connected nets, all of them corresponding to F-faces, have been determined for KTP. The order of morphologica importance (MI) of these F-faces is determined by comparing the first neighbour interaction ionic bond energies. Three different titanyl chain dissociation models have been used. The results have been compared with experimental data. The best agreement between theoretical and experimental data occurs, when using a titanyl association model. © 1990.
