摘要： Provided is a method for preparing non-magnetic nickel powders. The method include (a) heating a mixture including a nickel precursor compound and a polyol to reduce the nickel precursor compound to nickel powders with a face-centered cubic (FCC) crystal structure, and (b) heating the resultant mixture of step (a) to transform at least a portion of the nickel powders with the FCC crystal structure to nickel powders with a hexagonal close packed (HCP) crystal structure.
摘要翻译：提供一种制备非磁性镍粉的方法。该方法包括（a）加热包含镍前体化合物和多元醇的混合物以将镍前体化合物以面心立方（FCC）晶体结构还原成镍粉末，和（b）加热步骤（a ）以将具有FCC晶体结构的至少一部分镍粉末转变成具有六方密堆积（HCP）晶体结构的镍粉末。

摘要： Provided are non-magnetic nickel powders and a method for preparing the same. The nickel powders are non-magnetic and have a HCP crystal structure. An exemplary method includes (a) dispersing nickel powders with a FCC crystal structure in an organic solvent to prepare a starting material dispersion, and (b) heating the starting material dispersion to transform the nickel powders with the FCC crystal structure to the nickel powders with the HCP crystal structure. The nickel powders do not exhibit magnetic agglomeration or aggregation phenomenon. Therefore, exemplary pastes for inner electrode formation in various electronic devices, which contain the nickel powders of the present disclosure, can be provided in a relatively uniform, well-dispersed state because of the reduced aggregation and agglomeration of the nickel powder. Also, inner electrodes made of the nickel powders can have a low impedance value even at high frequency band.
摘要翻译：提供非磁性镍粉末及其制备方法。镍粉是非磁性的，具有HCP晶体结构。一种示例性方法包括（a）将FCC晶体结构的镍粉分散在有机溶剂中以制备原料分散体，和（b）加热原料分散体以将具有FCC晶体结构的镍粉转化为镍粉， HCP晶体结构。镍粉末不会发生磁性聚集或聚集现象。因此，由于镍粉的聚集和聚集减少，所以可以以相对均匀的，良好分散的状态提供包含本公开的镍粉末的各种电子器件中的内部电极形成的示例性糊料。此外，即使在高频带，由镍粉制成的内电极也可以具有低阻抗值。
