The vast majority of single rare earth metals and their intermediate alloys are used to produce new rare earth metal materials such as neodymium iron boron, samarium cobalt permanent magnet and super magnetostriction and non-ferrous metal alloys such as AI-RE, Mg-RE, Cu-RE, Zn- RE, W-RE, Mo-RE, etc. In addition, there are a few rare earth […]

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The most important properties of tungsten are high melting point and high density. Meanwhile, the hardness is high and its ductility is poor to other refractory metals. All the properties make tungsten metal hard to be machined, here we will introduce […]

Rare-earth intermetallic compounds are metal compound phases formed between rare-earth metals and other metals or similar metals. They mainly use the special physical and chemical properties of rare-earth intermetallic compounds to prepare new rare earths for various purposes using various processing and manufacturing techniques. Functional Materials. At present, there are the following rare earth metal […]

Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high temperature pyrolysis reaction by chemical vapor deposition method. Speaking of boron nitride, we must first talk about […]

Magnetism is the basic property of matter as well as force, heat, electricity and light. Materials with ferromagnetism are usually called magnetic materials. The biggest characteristic of magnetic materials is the hysteresis behavior, that is, the magnetization M changes with the external magnetic field. When H returns from a certain state to zero, M still […]
