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 […]
If you haven’t already, you should read this article on the rare earth elements. This article will discuss rare earth metals and rare earth oxides. Hopefully, you’ll find this information useful. The rare earth elements are essential for many applications, including computers, electronics, batteries, and more. Listed below are some common uses for these elements. […]
The atomization method is a powder preparation method in which a fast-moving fluid (atomization medium) impacts or otherwise breaks the metal or alloy liquid into fine droplets, and then condenses into a solid powder. The atomized powder particles not only have the same uniform chemical composition as the established molten alloy, but also due to […]
Titanium and its alloys have many advantages as surgical implant materials, such as lowdensity, high strength, good toughness, good biocompatibility, non-toxicity,low elastic modulus, good corrosion resistance, and low X-ray absorption rateEtc., thus occupying an increasingly important position in medical metalmaterials. Titanium and its alloys can be used for the repair and replacementof human hard tissues, […]
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 […]
