Special refractories mainly include high melting point oxides, high melting point non-oxides, and the derived composite compounds, cermet, high-temperature coating, high-temperature fiber, and its reinforcing materials. Among them, non-oxides with a high melting point are usually called refractory compounds, which also include carbides, nitrides, borides, silicides, and sulfides. Although the cost of special refractories is […]
Refractory metal materials mainly refer to tungsten, molybdenum, tantalum, niobium, rhenium, and vanadium, all of which are materials with a melting point above 2000 degrees Celsius. Refractory metal materials and their alloys have the characteristics of high melting point, high strength under a high-temperature environment, strong corrosion resistance to liquid metal and processing plasticity. Refractory […]
