  • Tungsten
    be used in aircraft applications, by the military in its weapons, in X-ray shielding, and even some consumer goods applications. Light bulb filaments are usually made of unalloyed tungsten. Cutting tools are often made of tungsten carbide. Finally, tungsten is also an element of some of the modern super
  • Carbon Fiber Heating Element Technology
    to normal heating materials like resistive elements or tungsten filaments, long carbon fiber has two distinct features that are superior to those heating systems in radiant applications: The carbon fiber heating element is extremely efficient as it transfers 98% of the electricity into heat by light
  • Analysis of Trace Elements in Tungsten Carbide using the Teledyne Leeman Labs Prodigy DC Arc
    ratio for each analyte of interest. An example profile is shown in Figure 1. The figure. is based on a time-resolved analysis (TRA) scan of a 500 ppm multi-element standard in a tungsten. matrix obtained over the course of a DC Arc burn that lasted 60 seconds. 3. Figure 1. Time-Resolved Analysis Scan
  • What is a Resistance Temperature Detector (RTD)?
    Resistance Temperature Detectors / RTD / RTDs What is a Resistance Temperature Detector? Resistance Temperature Detectors (RTD), as the name implies, are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length
  • Design / Installation Notes: Shortwave Emitters (.pdf)
    emitters infrared source is from a tungsten filament located in the center of the emitter. The protective element that surrounds the tungsten in made from clear fused quartzglass. This is evacuated and sealed and provides protection for the filament from oxygen, and provides against convection
  • Secure Attachment in Pulsed Power Applications
    accomplished by mounting the resistive element (chip) to a heat sink, which is then in turn mounted to a cold plate. Overheating of the resistive film is to be avoided as it can cause a resistance shift. This shift will interfere with the carefully designed RF impedance match. For the highest
  • Alloy Steel
    alloy steels: aluminum, chromium (to 3.99%), cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium or other element added to obtain an alloying effect. Technically, then, tool and stainless steels are alloy steels. In this chapter, however, the term alloy steel is reserved
  • Electricity from light gets hot
    a thermophotovoltaic device. Thermophotovoltaic systems generate electric current from light emitted by superheated materials. Photo by Donna Coveney, MIT To do so, they burn fuel to heat a cylindrical tungsten element till it's white hot. The element's surface is covered with microscopic pits called
