“…Therefore, rare earth metals prepared by this method have high impurity concentration and should be purified before application. Vacuum distillation was widely used in industry to remove reductant metals in order to obtain high purity rare earth metals [48][49][50][51]. Vacuum distillation means that rare earth metals are separated from impurities under high temperature and high vacuum.…”

“…[ 20–22 ] It was indicated that Mn is extremely volatile in high‐temperature melting steel under vacuum. [ 23 ] Furthermore, the vacuum chamber will be exposed to air after breaking the vacuum in the industrial RH (Ruhrstahl–Hereaeus) production process, resulting in the inevitable oxidation of the Mn deposited on the furnace refractories at a certain high temperature. The Mn oxides on the interaction between the refractory and melting steel have strongly affected the service life of the reactor, steel cleanliness, and production safety.…”
