Chemistry.
- : a gray, hard, rare, metallic element occurring in columbite and tantalite and usually associated with niobium: used, because of its resistance to corrosion by most acids, for chemical, dental, and surgical instruments and apparatus. Symbol: Ta; atomic weight: 180.948; atomic number: 73; specific gravity: 16.6.
Examples
The raw materials— tin, tantalum, tungsten and gold—were dubbed “conflict minerals.”
In China, for example, tungsten, tantalum, tin and gold are mined and ore is imported from other countries.
Tantalum helps you send text messages, tin is the solder on every circuit board and gold is the little connecting piece.
In 2012, Intel began producing microprocessors with conflict-free tantalum, a sign that conflict-free efforts were progressing.
Tantalum is used to protect interconnects inside microprocessors.
More efficient lamps have been devised with filaments of the metals tantalum and tungsten (Fig. 274).
The oxide of tantalum dissolves in the bead, but gives no colour.
Chemically related to vanadium are the two elements tantalum and columbium or niobium.
How are you going to separate out the tantalum and the others you want from the ones that you don't want?
I brought along a piece of platinum from the power plant, and something that I think is tantalum from Barkovis' description of it.
