by:Maghard      2020-09-27
Physical and chemical properties of rare earth magnet: one is the lack of sulfide and sulfate ( Only a very few) , which showed that the rare earth elements have oxyphilic sex; Second, rare earth silicate mainly island, no layer, frame and chain structure; 3 it is part of the rare earth minerals ( Especially complex oxide and silicate) Presents the amorphous state; Four is the distribution of rare earth minerals, in the magmatic rocks and pegmatite is given priority to with silicate and oxide, in hydrothermal deposit and weathering crust deposit is given priority to with fluorine carbonate and phosphate. Most of yttrium rich mineral occurrence in granite rock and its associated pegmatite, pneumatolytic hydrothermal deposits and hydrothermal deposit; Five is a rare earth element because of its atomic structure, chemical, and similar crystal chemistry and often in the same mineral symbiosis, the family of cerium rare earth and rare earth element yttrium family often exists in a mineral, but this kind of element is not the same, some minerals containing cerium rare earth is given priority to, the family is given priority to with the family of yttrium some minerals. In has been found more than 250 kinds of rare earth minerals and mineral containing rare earth elements, suitable for today's only more than 10 kinds of mineral smelting and condition of industrial minerals: A magnet classification. Temporary ( Soft) A magnet. Meaning: magnetic short, when after you remove the magnet magnetic disappeared. b。 Example: nails, wrought iron, B. Permanent ( Hard) A magnet. Meaning: after magnetization, can retain magnetic in long time. b。 Example: the steel nail magnet company is the specialized production ( Ndfeb) Powerful magnet company, has factories in dongguan city based wangniudun pier town.
