  • Refractory Metals
    Refractory metals are characterized by their extremely high melting points, which range well above those of iron, cobalt, and nickel. They are used in demanding applications requiring high-temperature strength and corrosion resistance. The most extensively used of these metals are tungsten
  • What Are Refractory Metals?
    properties: Besides. filament, because of its high melting. their use in many electrical and. point and good non- sag characteristic,. electronic applications, refractory. will withstand thousands of on-off. metals are often used as heat. cycles and still remain intact. sinks...this semiconductor
  • Refractory Hard Metals
    Refractory hard metals (RHMs) are a ceramiclike class of materials made from metal-carbide particles bonded together by a metal matrix. Often classified as ceramics and sometimes called cemented or sintered carbides, these metals were developed for extreme hardness and wear resistance. The RHMs
  • Thermographic Monitoring of Refractory Lined Petroleum Refinery Equipment
    . Refractory is a temperature-resistant lining similar to concrete that is used to line refinery equipment that operates at very high temperatures. The refractory lining protects the outer shell of the piping and vessels from the hot gas and catalyst circulating inside the process plant. Failure of refractory
  • Advanced Reactor System for the Fine Control of Properties of Molybdenum Powder (.pdf)
    In the refractory metal industry, fine-grain molybdenum (Mo) powder is usually produced by a two-stage reduction process. Both Ammonium Di-Molybdate (ADM) and Molybdenum Trioxide (MoO3) can be the starting materials with hydrogen (H2) as the reducing gas in either case. The first stage
  • Tungsten
    Tungsten is a heavy metal that can be classified as a refractory metal, i.e., one with a high melting point. Refractory metals can be useful for their strength at high temperatures and their resistance to corrosion. Tungsten is difficult to melt, so commercial non-alloyed tungsten is produced
  • DynaGuard Flexible Insulation Used in Rotory Kiln Applications (.pdf)
    refractory block and the steel shell it will require properties that will. withstand both the weight of the refractory and the movement of the individual. blocks, and rings of blocks, caused by the constant rotation of the kiln. If the. insulation is too soft, it will compress to the point where
  • Maintenance for Energy Efficiency (.pdf)
    is key to staying competitive in today's global economy, and now is the time for evaluating the performance of your furnaces and kilns. Key to the energy efficiency of your furnaces and kilns is the job the refractory insulation lining is doing. It is an unfortunate fact that although refractory
