Metallurgy is a domain of materials science and engineering that encompasses both the processes involved in procuring metal from ores, typically termed extractive metallurgy, and the processes involved in working and shaping metals to produce usable materials and products, termed process metallurgy. Metallurgy can also be separated into ferrous metallurgy, which concerns the production and use ...
The rare earth promoted catalysts were prepared by a wet impregnation technique . An aqueous solution of nickel nitrate and rare earth compounds were added to 2 g of 20 ~ 40 mesh support, and the samples were dried and subsequently calcined in air at high temperature, then sieved before use.
High-temperature resistance metals are also known as refractory metals. These metals are much harder at room temperature and usually have a melting point of above 2000 degree Celsius. The term 'refractory' is used for these materials in specific fields including engineering, material sciences and metallurgy.
Tungsten Carbide Powder: Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. Tungsten Carbide (WC) Nanoparticles, nanodots or nanopowder are black spherical high surface area particles.
1. Graphene. Brief introduction. Graphene is a honeycomb two-dimensional film formed by carbon atoms with sp2 hybridization. It is a monolayer sheet structure separated from graphite, and it is also the thinnest new material currently known.The tensile strength and elastic modulus of graphene are 125Gpa and 1.1tpa, respectively, and its strength is 100 times that of ordinary steel.
Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has a much better purity level and density. Stanford Advanced Materials provide PBN crucibles with high purity and competitive price. We offer tubes, sheets, LEC crucibles, MBE crucibles, VGF crucibles and other products made by a CVD process with PBN material.
Description of Anode Basket. The anode basket is light in weight, corrosion-resistant and has a layer of oxide film on the surface. Under normal plating conditions, the oxide film can prevent the current from passing through the anode basket and direct current to the anode material in the anode basket.
