Didymium Oxide (PrNd)xOy CAS 11141-21-2 For Electrolytic Preparation Of Pr-Nd Metal

Praseodymium neodymium oxide is a compound composed of praseodymium and neodymium, usually appearing as a gray or tan powder. It is easy to absorb water and inhale, so it needs to be stored in a dry place to prevent deterioration. Neodymium oxide has excellent chemical and physical properties and is widely used in many fields.
In the field of magnetic materials, praseodymium neodymium oxide is an important raw material for the manufacture of high-performance Ndfeb permanent magnet materials, which are widely used in electronic equipment such as motors, generators and transformers. Its strong magnetic crystal anisotropy and high magnetic saturation make it show high coercivity in the magnetic field. In addition, praseodymium and neodymium oxide also show an important role in the fields of laser materials, ceramic materials and medical materials. In the laser field, it is used to manufacture high-efficiency lasers and optical fiber communication equipment; In the ceramic field, its high insulation, wear resistance and corrosion resistance make it ideal for high temperature and high pressure environments; In the medical field, praseodymium and neodymium oxide as an additive can improve the performance of materials such as medical glass and syringes.

Description

Didymium oxide, appearance is gray or brown powder, easy to absorb water and inhale, it must be stored in a dry place, not in the open air. Didymium oxide is the raw material of praseodymium and neodymium (namely praseodymium and neodymium alloy). Didymium oxide are melted at high temperature to form metal praseodymium and neodymium. In the process of rare earth electrolysis, the requirements for the physical properties of didymium oxide are as follows: the dissolution speed of didymium oxide in the electrolyte is fast, the furnace bottom precipitation is less; the flying loss is less, the loss of didymium oxide is low; the wear index is small, the strength is large, and the particles are less broken in the process of screening, mixing, transportation, loading and unloading; the particle fluidity is good. The physical properties of didymium oxide are mainly characterized by specific surface area, particle size and wear index.

Used

Didymium oxide is widely used in magnetic materials, glass, ceramics, catalysis, electronics and other fields, especially in the application of praseodymium neodymium iron boron magnetic materials. With the development of science and technology, the application of praseodymium, neodymium, iron and boron magnetic materials is developing, especially in the preparation of didymium oxide, the demand for large particles of didymium oxide is increasing obviously, and the preparation of didymium oxide with large particles avoids fine particles.
