If you centrifuge salt water you'll get a concentration gradient and if it's saturated at the end you'll get salt crystals. Alloys aren't solutions, so it won't work, but you'll still get a gradient. You could iteratively refine by removing the unwanted half from two spins and combining the wanted halves for a third spin. I'm not sure this is practical...
- wycx 11y agoDo people actually do this? Can the accellerations you reach with laboratory centrifuges induce sufficient concentration gradients in salt solutions? Surely the salt begins dissolving as you stop accellerating?
- ectoplasm 11y agoNo, people don't do this in practice, and I haven't seen it done, but it could be done if you had the right equipment and a salty enough solution. Just decant the water at the end, salt doesn't dissolve immediately. I don't know how fast you'd have to go.
