Tantalum and Niobium Applied in Electronic Technique
Niobium and tantalum have important applications in electronic technique, superconducting materials, heat-resistant alloys, hard alloy, alloy steel, chemical corrosion resistant materials, etc..
In the electronic technique, niobium and tantalum have high melting point, good electron emission ability and inspiratory capacity, so tantalum and niobium can be used as electron tubes and other electronic vacuum devices.
In the electronic technology, due to niobium and tantalum are featured by high melting point, strong electron emission ability and inspiratory capacity, so tantalum and niobium can be used as electron tubes and other electronic vacuum devices. For example, tantalum is able to be applied as anode, grid electrode, separately heated cathode and other heating elements of electron tube. Especially titanium can be used as components of large power oscillation tube. Sometimes, these components of large power oscillation are made of niobium and tantalum alloy and niobium instead of using tantalum.
Tantalum electrical condenser of solid electrolyte has the advantages of small volume, large capacity, big insulating resistance. Tantalum electrical condenser of solid electrolyte can be used at temperature range of -80 ℃ to 200 ℃. Min tantalum electrical condenser are widely used in radio-transmitting station, radar electronic computer and other equipments.
Electrolytic condenser and rectifier made of tantalum, when the positive electrode is oxidated, tantalum electrolytic condenser and rectifier can form stable oxidation film. This oxidation film is stable in acidic electrolyte and it only allows electric current to one-way run from the electrolyte to metal.
Niobium and tantalum alloy and metal niobium can also make electrical condenser, but electrical condenser made of tantalum can resist higher electric voltage and has less residual electric current.
