Isotopes of Copper. Copper (Cu) possesses two stable isotopes, 63 Cu and 65 Cu, as well as several more radioisotopes. The great majority of radioisotopes have half-lives of minutes or less, with 67 Cu having the longest half-life at 61.8 hours. Unstable copper isotopes with atomic masses less than 63 are likely to undergo β + decay, whereas those with masses …
Based on the strength and microstructure tests, the effects of the hydantoin epoxy resin content and curing time on the mechanical properties and microstructure of copper tailings specimens were studied. The results showed that the strength of the solidified specimens was increased to 20.84 MPa with 30 wt.% addition of hydantoin epoxy resin.
