Sichuan’s project for producing 1,800 tons per year of electronic-grade rare earth fluorides and lithium fluorides has been registered 2026-02-13 15:49:05 On February 10th, Mianyang Lihai Electronic Technology Co., Ltd.’s project for producing 1,800 tons per year of electronic-grade rare earth fluorides and lithium fluorides was registered on relevant websites. The details of the project are as follows: Project name: 1,800 tons per year production of electronic-grade rare earth fluorides and lithium fluorides； Construction unit: Mianyang Lihai Electronic Technology Co., Ltd ； Construction location: Mianyang City, Sichuan Province ； Filing date: February 10, 2026 ； Electronic-grade rare earth fluorides: These are ultra-high-purity rare earth fluorides, with purities typically ranging from 4N to 5N or even higher. They represent advanced electronic materials that fall at the intersection of fluorine chemistry and advanced processing of rare earths. The main types include lanthanum fluoride, yttrium fluoride, erbium fluoride, and ytterbium fluoride. Such materials possess strong chemical stability, resistance to extreme temperatures, and excellent optical properties. They are used in high-tech applications such as semiconductors, optical coatings, laser fibers, solid-state batteries, and display devices, and serve as key materials in the industries related to electronic information and new energy. Lithium fluoride: Lithium fluoride is a key basic material for electron-grade, high-purity fluorides. It is primarily used in lithium battery electrolytes, solid-state batteries, optical crystals, and the nuclear industry. It requires high purity and presents significant technical barriers; it is therefore a core material in the new energy and high-end electronics supply chains. Regarding Mianyang Lihai Electronic Technology Co., Ltd.: Mianyang Lihai Electronic Technology Co., Ltd. was established on October 22, 2014; it is an electronic technology company located in Fucheng District, Mianyang City, Sichuan Province. The company’s main business activities cover the fields of electronic products and electronic technology services, with a focus on the research and development, production of electronic products, as well as related technical services.
