We compared a stabilized-temperature L'vov platform furnace containing an end-heated graphite atomizer (HGA) and transverse Zeeman background-correction system with a side-heated furnace system (transversely heated graphite atomizer; THGA) containing a longitudinal Zeeman background-correction system for the determination of aluminum in plasma and urine. The regression statistics for the correl...

Annealing furnaces are used to heat steel in order to change its chemical structure. In this paper we model an electric radiant furnace. One of the major defects in steel strips processed in such furnaces is a wave-like pattern near the edges of the strip, apparently due to extra heating near the edges. The aim of the paper is to model this effect and provide a way to calculate the elevated tem...

High quality heating device made of ferromagnetic alloy (thermal seed) was developed for hyperthermia treatment of cancer. Ferromagnetic seeds of PdNi, PdCo and CuNi are prepared by induction furnace and subsequent heat treatment. Magnetic induction and hysteresis loops are measured as functions of temperature. The power dissipated from each seed was calculated from the area enclosed by the hys...

This paper explores the physical mechanisms responsible for experimental observations that led to the definition of ‘‘photo-induced hydrogen outgassing of glass’’. Doped borosilicate glass samples were placed inside an evacuated silica tube and heated in a furnace or by an incandescent lamp. It was observed that hydrogen release from the glass sample was faster and stronger when heated by an in...

Thermophilic actinomycetes, associated with a hypersensitivity pneumonitis, may be found in compost but also have been detected in heating systems of office buildings. This study was designed to determine whether these organisms were present in residential heating systems. Furnace dust or humidifier water of 12 of 20 homes contained thermophilic actinomycetes, indicating that the organisms may ...

Metallic nanoparticle inks are used for printed electronics, but to reach acceptable conductivity the structures need to be sintered, usually using a furnace. Recently, sintering by direct resistive heating has been demonstrated. For a microscopic understanding of this Joule heating sintering method, we studied the entire process in real time inside a transmission electron microscope equipped w...

Structural changes and properties of zirconium alloy subjected to the thermal shock in the solar furnace were investigated. Specimens were prepared from unirradiated cold-worked RBMK Zr-2.5Nb fuel channel pressure tube material after adding hydrogen to the sections of the tubes up to 150 ppm. Tests were done at temperatures up to 1460 C and heating rates 50-83 C per second. After thermal treatm...

We report a multipurpose furnace designed for studies using synchrotron radiation on polycrystalline materials, namely, metals, ceramics, and (semi)crystalline polymers. The furnace has been designed to carry out three-dimensional (3D) x-ray diffraction measurements but can also be used for other types of synchrotron radiation research. The furnace has a very low thermal gradient across the spe...

We report on the Czochralski method for single silicon crystal growth and discuss heat and mass transfer and defect formation in the crystal. A re ector was used for separation of the heating and cooling areas in the furnace enabling us to speed up crystal growth. The melt ow to stabilize the temperature distribution in a crucible was controlled using transverse magnetic elds in a large-scale s...
