Fuel cells are new energy technologies with broad application prospects. Carbon-supported platinum-based catalysts (Pt/C) are the most commonly used fuel cell electrode catalysts, but the poor stability and high cost of Pt/C severely limit their large-scale applications.  Covalent carbides, silicon carbide , and boron carbide , have excellent physicochemical stability due to their extremely strong covalent bonds, and have become important basic materials for the preparation of fuel cell catalysts with high stability and low cost. Hydrogen is widely used in many fields such as industry and medical treatment, and it is also one of the most commonly used fuels for fuel cell anodes. Platinum-based catalysts are still the best hydrogen production catalysts. Silicon carbide (SiC) is a compound with very stable physicochemical properties. Composite nanomaterials with SiC as an important component are also often used as supports for platinum-based catalysts. B4C is a highly stable covalent

Little radiation Medical zirconia is cleaned and processed, leaving a small amount of alpha ray residue in zirconium, which penetrates to a small depth of only 60 microns. High density, high strength, metal-free inner crown Zirconia has unique resistance to cracking and strong curing performance after cracking. It can be used to make more than 6 units of ceramic bridges. Although there is no metal support, it has high strength, and its refractive index is basically close to that of natural teeth, with dense edges and high precision, and has excellent aesthetic effects: Zirconia ceramics are usually yttrium-stabilized zirconia ceramics with high flexural strength. Compared with other all-ceramic restoration materials, the strength advantage of zirconium dioxide material allows doctors not to rub the patient's real teeth too much. Excellent aesthetic effect Zirconia all-ceramic teeth have a realistic and beautiful appearance, solid and wear-resistant, similar in color

Silicon carbide is a synthetic carbide with a molecular formula of SiC. It is usually formed by silicon dioxide and carbon at a high temperature of 2000°C or higher after electrification. Due to its high hardness, high wear resistance, high corrosion resistance and high-temperature strength, SiC is used in various wear-resistant, corrosion-resistant and high-temperature resistant mechanical parts. Chemical properties Oxidation resistance: When silicon carbide is heated to 1300°C in air, a protective layer of silicon dioxide begins to form on its crystal surface. With the thickening of the protective layer, the internal silicon carbide is prevented from being oxidized, which makes the silicon carbide have better oxidation resistance. However, when the temperature reaches 1900K (1627°C) or higher, the silicon dioxide protective film begins to disappear, and the oxidation of silicon carbide intensifies.　　 Acid and alkali resistance: due to the silicon dioxide protective film on its surfa
