Stanford Magnets

Analysis Methods of NdFeB Magnets The chemical composition analysis of NdFeB Magnets  generally includes: 1- Chemical composition analysis of raw materials, including the chemical composition of rare earth metal raw materials, as well as the chemical composition of industrial pure Fe, B-Fe alloys and other metals, such as Ga, Al, Nb, Zr, etc.; 2- The chemical composition of the magnet. The analysis is required for unknown magnets or problems with magnets, not necessary if the product is of normal quality. The chemical composition of the magnet includes rare earth metal elements, such as Nd, Pr, Ce, Dy, Ho, Gd, Tb, etc., and other metal elements, such as Cu, Al, Nb, Zr, Ga, Co, Ti, etc.; 3- Content analysis of other non-metallic elements, such as hydrogen, oxygen, carbon and other elements content analysis. ICP emission spectroscopy is an analytical method that combines Inductively Coupled Plasma (ICP) and Atomic Emission Spectroscopy (AES). Principles of ICP The atoms or ions of th...
