Relevance
This unique metal with a high melting temperature is a complex technological material. Since its opening almost 100 years it was considered a harmful impurity in the ore. At Plaka of polymetallic ores, with a mixture of wolframite, decreased output of finished metal, tungsten, as it were ate it. No coincidence that the name Wolfram means wolf froth. And now it is indispensable in electrical engineering and the production of alloys with special properties.
Technical characteristics
Tungsten heads to the group of refractory metals, refractory it is ahead of only carbon, under normal conditions the metal does not react with any chemical substances, Structure of body-centred cubic lattice. Density it is identical to gold.
