Differing plutonium metal alloys containing known amounts of impurities were studied for the two systems. Zone refining was done using plutonium rods. The presence of oxygen had a large negative effect on zone refining effectiveness. Decreasing travel speed of the ...

WebMar 29, 2024 · A novel technique was developed to purify 99.99682% tin by zone refining in an argon atmosphere. The impacts of zone melting conditions, such as the segregation coefficient, zone melting rate, and the number of zone melting passes, on the purity of refined tin were experimentally studied.

The small molten segment remains fixed in place between the solid portions of the rod due to surface tension. Using steam refining to remove the most stubborn impurities, such as boron, he produced silicon famous mj songs
