3900 °C), high hardness and elastic modulus, and good resistance to chemical attack. Given these properties, HfC is an attractive material for applications in the fields such as nuclear rocket propulsion, nuclear reactors, the space aircraft indWhat is hafnium carbide?Hafnium carbide (HfC) belongs to so-called "hard metals." In the periodic table, these materials are carbides of transition metals of groups IV–VI. HfC is a promising candidate for extremely high-temperature applications owing to its high melting point (>3900 °C), high hardness and elastic modulus, and good resistance to chemical attack. Given these properties, HfC is an attractive material for applications in the fields such as nuclear rocket propulsion, nuclear reactorsHafnium Powder is a metal made from hafnium. The most common method to prepare hafnium from sponge hafnium involves hydrogenation and deshydrogenation. Purity>99%Particle Size : 5-10 Micron Hafnium Nanopowder: Hafnium Hafnium on the periodic table : Group 4, Atomic Number d-block, Mass 178.586. Hafnium a shiny silvery metal. It's resistant to corrosion due to the tough oxide layer that forms on its surface. Hafnium metallicis unaffected by acids or bases except hydrofluoric. Hafnium element caHafnium hydroide, chemical formula: HfH2, is a black-gray powder that's mainly used for the atomic power industry and aerospace industries. Purity: 99%Particle size: 320mesh Hafnium Hydroide HfH2 powder: A grey-black powder, Hydride Hafnium (HfH2) can be found. When the temperature exceeds 300 deg C, the hydride becomes hydrogen. HFH1.86 results when hafnium reaches a higher temperature. Hafnium Hydride HfH2 Powder CAS 13966-92-2: HfH2 Powder can be obtained in most quantities. ConWhat property does hafnium boreide have? Hafnium boride This crystal is gray with a metallic luster. It has a melting temperature of 3250°C, and it is known for its high conductivity. Hafnium boride has little reaction with other chemical reagents at room temperature. Hafnium Boride is made by heating hafnium dioxide with boron carbide (or boron oxide) and carbon powder. Hafnium-boride powder can be prepared by using the variable current laser beam gas phase technique. It is a novel ceramWhat is hafnium caride? Hafnium carbonide (HfC), is a chemical compound made of hafnium, carbon. It is one of most refractory binary substances known, with a melting temperature of 3900degC. Its oxidation resistance is low and it oxidizes at temperatures of 430°C. This compound could be part of future spacecraft's heat shield. Carbonization often lacks carbon so it is usually described as HfCx (x = 0,5 to 1,0). It has a cubic crystal structure (salt rock), of any x values. Hafnium carbide caReview of hafnium Hafnium can be described as a chemical element. Its symbol is Hf, and its atomic numer is 72. Hafnium, which is a shiny silvery-gray tetravalent transformation metal has the same chemical properties as zirconium and can also be found in zirconium minerals. Dmitri Menedeleev had predicted it's existence in 1869. But it wasn’t until 1923 that Coster & Hevesy discovered its existence, making it one of the few stable elements to have been discovered. There are six natural stableHafnium carbide, also known as HfC (hafnium-carbonide), is a chemical mixture of hafnium & carbon. This binary compound is among the least refractory. It has a melting point around 3900°C. The compound is resistant to oxidation, but it can be oxidized at temperatures as low and as high as 430°C. It may also be used in the heat shield on future spacecraft. Is hafnium carbide toxic? Animal studies have shown that hafnium oxychloride is toxic through the intraperitoneal route. Hafnium has notWhat's hafnium Diboride Powder? Hafnium diboride can be described as an ultra-high-temperature ceramic that is made of hafnium, boron and other elements. It's an uncommon ceramic that has high heat conductivity and conduction. It is a grey, metallic substance. Hafnium dioxide has a hexagonal structure and melts at approximately 3,250 Celsius. Hafnium diboride's resistance to oxidation is affected by temperature and pressure. At 1 atm pressure and 1500°C, the protective oxide layer forms. HfB2's" name="description" />
