基本信息
| 应用 | Cerium(III) fluoride is used to make Lewis acid. It is considered to be the most effective glass polishing agent for high precision optical polishing. Cerium fluoride used as a core additive to improve the properties of the eventual weld. The fluoride provides stability to the arc and also modifies the behavior of the molten metal flowing into the weld. |
