Materials with the highest melting point: Carbides, nitrides, metal tungsten?
When it comes to the world, we can always think of a few. For example, the Yellow River, the mother of the Chinese nation, is the river with the largest sand content in the world; Meng Jiangnuundefineds "Great Wall", "crying", is the longest wall in the world; and, for example, diamond, which symbolizes love and can be used as a cutting tool, is the hardest material in nature. However, what I want to introduce today is the most difficult to melt in the world. This also has to be subdivided, is it the most refractory pure metal in the world? Or the most refractory material in the world? The answer for the former is pure tungsten, while the latter is a powder mixture recently synthesized by Russian scholars, carbides and nitride containing hafnium.
As is well known, tungsten (W) is the worldundefineds highest melting point of pure metal, which means it is the most refractory, with a melting point of 3156.85 Kelvin (3430. degree. C.). The most refractory material in the world is a powder mixture of carbon-containing carbide and nitride with a melting point of 4400 Kelvin (4126.85. degree. C.). This is a few days before the Russian Far East Federal University and the Far East Branch of the Russian Academy of Sciences were synthesized under extreme conditions. The high-temperature functional material is mainly applied to the fields of national defense military industry, aerospace, electronic information, energy, anti-chemical, metallurgy and nuclear industry, and has good application prospect. The next step in the study, according to a news from the Federal University of the Far East of Russia, is the optimization of the synthesis of the material and the in-depth study of the solid phase change process. The author suggests that the worldundefineds most refractory material, Ta4HfC5, has a melting point of 4200 Kelvin (3926.85. degree. C.). I canundefinedt help to sigh, this kind of carbide and nitride powder mixture material, can be said to be able to "be side-by-side with the sun"! The surface temperature of the sun is 5770 Kelvin (5496.85. degree. C.). Good at the back of the day, not all out, give us a sun, otherwise, how can the "to fly to the sky" and the sun shoulder side by side ". Thatundefineds what Iundefinedm talking about, The powder mixture material is obtained by the research team of the Institute of Natural Science of the Far East Federal University of the Russian Far East and the Institute of Chemical Research of the Far East Institute of the Russian Academy of Sciences by means of a pulse-flame sintering process. In 2016, we specialize in the research of new materials in the fields of military industry, aerospace, biomedicine, nuclear waste safety treatment, ecological environment monitoring and so on.
