Product Description
Small crystal of potassium tetrafluoronickelate, approximately 0.2 x 0.3 x 0.2 inches, with some surface degradation, in small plastic box sealed with dessicant. N2NiF4 crystals are important in the development of high-temperature super-conductors. The crystal surface does have some oxidation, as can be seen from the photos.
