uhp 650 graphite electrode
Physical properties of uhp 650 graphite electrode
The pure uhp 650 graphite electrode is colorless, while the industrially produced brown to black is due to impurities containing iron. The rainbow-like luster on the crystal is due to the silicon dioxide protective layer on the surface.
Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, uhp 650 graphite electrode has many other uses besides being used as abrasives. For example, the uhp 650 graphite electrode powder is coated on the turbine impeller by a special process. Or the inner wall of the cylinder body can improve its wear resistance and prolong its service life by 1 to 2 times; the high-grade refractory material made of it has heat shock resistance, small size, light weight and high strength, and has a good energy-saving effect.
The low-grade uhp 650 graphite electrode (containing about 85% SiC) is an excellent deoxidizer. It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel. In addition, uhp 650 graphite electrode is also widely used to make silicon carbide rods for heating elements. The hardness of the uhp 650 graphite electrode is very high, with a Mohs hardness of 9.5, second only to the world’s hardest diamond (grade 10). It has excellent thermal conductivity, is a semiconductor, and can resist oxidation at high temperatures.
There are at least 70 crystalline types of uhp 650 graphite electrode. α-uhp 650 graphite electrode is the most common kind of isomorphous crystal, formed at a high temperature higher than 2000 °C, and has a hexagonal crystal structure (like wurtzite). β-uhp 650 graphite electrode has a cubic crystal structure, which is similar to diamond, and it is produced below 2000 °C. The structure is shown in the figure on the page.
Although in the application of heterogeneous catalyst support, it is eye-catching because of its higher unit surface area than the α type, and another uhp 650 graphite electrode, the μ-uhp 650 graphite electrode, is the most stable, and it has a relatively high impact on collisions. Pleasant sound, but until today, these two types have not yet been commercialized. The above carbon companies-professionally operate various graphite electrode, uhp 650 graphite electrode, and provide you with them. Welcome to consult or buy at the store at any time.
