Web15 sep. 2024 · Rhenium Ionic liquid Microemulsion Mechanism 1. Introduction Rhenium has been studied and applied in metallurgy, military, aviation, chemical, and petrochemical industries, as well as biomedicine, because of its high melting point and hardness, corrosion resistance, etc. [1], [2], [3]. Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å).
