Tungsten Uses, Properties, & Facts Britannica
Webtungsten processing, preparation of the ore for use in various products. Tungsten exhibits a body-centred cubic (bcc) crystal lattice. It has the highest melting point of all metals, 3,410° C (6,170° F), and it has high conductivity for electricity. Owing to this unique combination of properties, it is used extensively as filaments for incandescent lamps, as electric … WebLight bulbs are manufactured with tungsten filaments because tungsten has an abnormally high melting temperature. But tungsten will catch on fire at such high temperatures, if the conditions are right. Combustion is caused by a reaction between two chemicals, which is set off when one of the chemicals has reached its ignition temperature.
