The German statutory accident insurance »DGUV« information 208-049 refers to the fact that thorium oxide-containing tungsten electrodes according to Section 4.2 (1) of TRGS 528 "may only be used for product-specific requirements (compelling technical reasons)" and that the provisions of the Radiation Protection Ordinance must be observed.
Thorium is a lanthanide (rare earth) material with potential nuclear power applications. It is presently used as a tungsten coating in electronic parts due to its high emission factor. In its fluoride and oxide forms, Thorium …
• Choose thorium-free tungsten electrodes such as those containing zirconium whenever possible. • Read, understand, and follow all information in the Material Safety Data Sheet (MSDS) for the selected tungsten electrode. • Use a high-efficiency dust collection system to capture particles created during the grinding of electrodes or
Radionuclide Basics: Thorium. Thorium (chemical symbol Th) is a naturally occurring radioactive metal found at trace levels in soil, rocks, water, plants and animals. Thorium is solid under normal conditions. There are natural and man-made forms of thorium, all of which are radioactive. In general, naturally occurring thorium exists as Th …
Th is a paramagnetic element. Th is dimorphic, transitioning from a cubic structure to a body-centered cubic structure at 1400 °C. It becomes a superconductor at temperatures below 1.4 K (-271.75 °C). The melting point of thorium oxide is 3300°C, making it the highest among the oxides. Color/physical appearance.
Our standard Pieces sizes average in the range of 3 mm, 4 -5 mm, 100 - 150 mm, 1/8" and 1/4". We can also provide Pieces outside this range. We also produce Thorium Oxide as pellets, tablets, powder, and sputtering target. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically ...
