tantalum helps you send text messages, tin is the solder on every circuit board and gold is the little connecting piece.
Tungsten, tantalum, tin and gold are used to produce many common consumer electronics devices.
The raw materials— tin, tantalum, tungsten and gold—were dubbed “conflict minerals.”
tantalum is used to protect interconnects inside microprocessors.
In China, for example, tungsten, tantalum, tin and gold are mined and ore is imported from other countries.
The tantalum filament was quickly followed by osmium and by tungsten in this country.
Just to make sure of cleaning up the last infinitesimal traces, though, I'm going to flash a getter charge of tantalum in it.
Later came the metalized carbon filament and finally the employment of tantalum or tungsten.
A century elapsed after its discovery before von Bolton produced the first tantalum filament lamp.
The oxide of tantalum dissolves in the bead, but gives no colour.
tantalum tan·ta·lum (tān'tə-ləm)
A hard heavy metallic element that is exceptionally resistant to chemical attack below 150°C and is used to make electronic components and surgical instruments. Atomic number 73; atomic weight 180.948; melting point 3,017°C; boiling point 5,458°C; specific gravity 16.7; valence 2, 3, 4, 5.
A hard, heavy, gray metallic element that is highly resistant to corrosion at low temperatures. It is used to make light-bulb filaments, surgical instruments, and glass for camera lenses. Atomic number 73; atomic weight 180.948; melting point 2,996°C; boiling point 5,425°C; specific gravity 16.6; valence 2, 3, 4, 5. See Periodic Table.
