Silicon carbide ceramics: One of the most popular bulletproof ceramic materials
Silicon carbide covalent bond is very strong, still has high strength bonding at high temperature, this structural characteristic gives silicon carbide ceramics excellent strength, high hardness, wear resistance, corrosion resistance, high thermal conductivity, good thermal shock resistance and o...Read more -
Comparison of properties of silicon carbide ceramics and alumina ceramics
Sic ceramics not only have excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also have the best mechanical properties at high temperature (strength, ...Read more -
How to use graphite disc root
Useful seals for pumps and valves depend on the overall condition of each component, especially the graphite disc device and conditioning. Before the winding device, firmly believe that the need for more graphite winding equipment has been in accordance with the site and system for useful isolati...Read more -
Economic analysis of green hydrogen production by electrolysis from renewable energy sources
More and more countries are beginning to set strategic goals for hydrogen energy, and some investments are tending to green hydrogen technology development. The EU and China are leading this development, looking for first-mover advantages in technology and infrastructure. Meanwhile, Japan, South ...Read more -
Progress and economic analysis of hydrogen production by electrolysis of solid oxides
Progress and economic analysis of hydrogen production by electrolysis of solid oxides Solid oxide electrolyzer (SOE) uses high-temperature water vapor (600 ~ 900°C) for electrolysis, which is more efficient than alkaline electrolyzer and PEM electrolyzer. In the 1960s, the United States and Germa...Read more -
International hydrogen | BP released 2023 “world energy outlook”
On January 30, British Petroleum (BP) released the 2023 “World Energy Outlook” report, emphasizing that fossil fuels in the short term is more important in the energy transition, but the global energy supply shortage, carbon emissions continue to increase and other factors are expecte...Read more -
Progress and economic analysis of ion exchange membrane (AEM) hydroelectrolysis for hydrogen production
AEM is to some extent a hybrid of PEM and traditional diaphragm based lye electrolysis. The principle of AEM electrolytic cell is shown in Figure 3. At the cathode, water is reduced to produce hydrogen and OH -. OH — flows through the diaphragm to the anode, where it recombines to produce o...Read more -
Proton exchange membrane (PEM) electrolytic water hydrogen production technology progress and economic analysis
In 1966, General Electric Company developed water electrolytic cell based on proton conduction concept, using polymer membrane as electrolyte. PEM cells were commercialized by General Electric in 1978. Currently, the company produces fewer PEM cells, mainly because of its limited hydrogen product...Read more
