CESIUM, IODINE, BARIUM, LANTHANUM, CERIUM, PRASEODYMIUM IODINE Atomic symbol: I Atomic weight: 126.90447 Atomic number: 53 Electron configuration: 2-8-18-18-7 Oxidation states: ±1, +5, 7 State of matter: solid Non-metal Discovered in 1811 by Bernard Courtois Boils at 184°C, melts at 113.5°C Notes: Iodine is bluish-black in color with a metallic luster, characteristic odor, and sharp […]
What are ultra-high temperature materials Ultra-high-temperature materials refer to the most heat-resistant high-grade materials that can be used as usual under severe environments such as stress and oxidation, and at an ultra-high temperature of about 2000°C. Research and application of ultra-high temperature materials 1. Refractory metal Refractory metals (W, Mo, Ta, Nb, Zr, etc.) […]
PALLADIUM, SILVER, CADMIUM, INDIUM, TIN, ANTIMONY, TELLURIUM PALLADIUM Atomic symbol: Pd Atomic weight: 106.42 Atomic number: 46 Electron configuration: 2-8-18-18-0 Oxidation states: +2, +4 State of matter: solid Heavy metal, ductile Discovered in 1803 by William Hyde Wollaston Boils at 2927°C, melts at 1552°C Notes: Palladium is a silver, white metal that also occurs as […]
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. Pyrolytic Boron Nitride (PBN) material has high purity, chemical […]
Titanium and its alloys have many advantages as surgical implant materials, such as low density, high strength, good toughness, good biocompatibility, non-toxicity, low elastic modulus, good corrosion resistance, and low X-ray absorption rate Etc., thus occupying an increasingly important position in medical metal materials. Titanium and its alloys can be used for the repair and […]
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 […]
High-density tungsten alloy, also known as tungsten-based heavy alloy, is a type of alloy made of tungsten as the matrix element (85% ~ 99% mass fraction) with the addition of Ni, Cu, Fe and other alloy elements by liquid phase sintering. The density is up to 16.5 ~ 19.0g / cc. The most commonly used are […]
A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available History General Motors (GM) and Sumitomo Special Metals independently discovered the Nd2Fe14B compound almost simultaneously in 1984. The research was […]
