Tantalum Capillary Description

Tantalum capillary is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Ta capillary is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. It has the fourth-highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors.

Tantalum Capillary Application

Tantalum capillary tube can be used as the filament lead tube of the cathode insulator in an x-ray tube, as a marker band in medicine and can be used as a thermocouple tube. Other uses include:

the filament lead tube

• Used in laboratory equipment.
• Used as a substitute for platinum.
• Used as the filament lead tube of the cathode insulator in an x-ray tube.
• Used in liquid tantalum electrolytic capacitors

Tantalum Capillary Packaging

Tantalum capillaries are carefully handled to prevent damage during storage and transportation.
