Title: Sublimation purification of inorganic fluoride
Inventor: SAKAGUCHI SHIGEKI
IPC: C01B13/14
Filed: 1986-11-21
Abstract: PURPOSE:To effect remarkable sublimation and removal of impurity metals from objective inorganic fluoride salts containing impurity metal compounds, without melting the inorganic fluoride, by carrying out sublimation purification while keeping large vapor-pressure difference between the inorganic fluoride and the impurity metal. CONSTITUTION:When the objective inorganic fluoride has high vapor pressure than the impurity metal fluoride, the fluoride is heat-treated in the presence of a metal oxide or water in the metal fluoride or in the treating atmosphere to convert the impurity metal fluoride to nonvolatile metal oxide and the objective fluoride is sublimed. When the inorganic fluoride has lower vapor pressure than the impurity metal fluoride, the amount of the metal oxide or water in the raw metal fluoride or in the treating atmosphere is reduced beforehand and the fluoride is heat-treated to effect sublimation and removal of the impurity metal while preventing the conversion of the impurity metal fluoride to nonvolatile metal oxide.
