易溶于水、液氧、氨水、乙醇中，微溶于丙酮，水溶液呈酸性，PH值约为4。有吸湿性，潮湿空气中很快潮解。干燥空气中缓慢风化，受热时会失去四个分子水，温度高于110℃时开始分解并形成碱式盐，继续加热生成棕黑色的三氧化二镍和绿色的氧化亚镍的混合物。接触尘沫及其他有机物，有时能引起燃烧或爆炸。用于镀镍、金属着色、镍催化剂、陶瓷褐色颜料、化学试剂等。 Nickel(II) nitrate hexahydrate, 99.999% trace metals basis is a highly pure (99.999%), with trace metal content ≤ 15.0 ppm. The product is designed for R&D applications of high-precision processes. It is suitable for use in a wide range of applications in catalysis, material science, electronics, electroplating, battery technology, chemical synthesis, analytical chemistry, and the production of pigments and coatings.
