Fabrication Method for Unoriented Phase I PVF2.
Abstract
Fabrication of unoriented phase I crystalline PVF2 is described wherein commercially available PVF2 phase II (crystalline form) is placed in a high pressure cell and its temperature is raised slightly over its melting point. The sample is then subjected to abrupt changes in high pressure and the temperature is dropped thereafter. The pressure is then reduced resulting in a product which contains both phase I and phase II forms of PVF2. The phase I content of the product varies from a few percent and up depending upon the pressure applied during the quenching step. (Author)
