Title: Yoon Sang Lee: Innovator in Zirconium Processing
Introduction
Yoon Sang Lee is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of materials science, particularly in the processing of zirconium. With a total of 3 patents, his work focuses on eco-friendly methods and innovative technologies.
Latest Patents
One of his latest patents is an eco-friendly smelting process for reactor-grade zirconium using raw ore metal reduction and electrolytic refining integrated process. This manufacturing method is characterized by self-propagating high-temperature synthesis (SHS) of a raw material containing zirconium raw ore and a reducing agent that is metal powder. This process prepares zirconium intermetallic compounds or zirconium nitride, followed by the recovery of high-purity zirconium through electrolytic refining of the reaction product from the SHS.
Another notable patent is an ingot-casting apparatus using uranium deposits. This casting apparatus includes a hermetically sealed chamber with a melt-heating portion to melt external uranium deposits. The melt-heating portion is tiltable, allowing the resulting liquid molten material to be discharged. The ingot-forming portion receives the molten material and cools it to solidify. Additionally, a salt-capturing portion is provided to solidify a salt gas produced during the melting of uranium deposits.
