Biologically, some bacteria use tungsten to reduce carboxylic acids to aldehydes. Pure tungsten is a stelel-gray to tin-white metal. Take for example the case of element 74 - or as we call it in English - tungsten. For this reason, this hard compound is sintered, a process that requires pressing and heating the powder form at high temperatures, to make products used in machining and cutting. Tungsten's primary application for over 100 years has been as the filament in incandescent light bulbs.
