Tantalum products are largely used in the chemical industries for their corrosion resistance and thermal conductivity. Tantalum resists corrosion as well as glass yet transfers heat better than nickel alloys. Overview Tantalum fabrication was developed for the production of chemical process equipment in the 1960s. While this technology is not new, it remains demanding with
Tantalum is a rare element that is highly prized for its applications in industry and emerging technologies. As a refractory metal, tantalum has a very high density (16.7 g/cm 3 at room temperature), a very high melting point (3017 C), and good mechanical strength at high temperatures.. Tantalum stands out from other refractory metals due to its extreme chemical inertness and electrical ...

Titanium is now a standard material of construction for many chemical processes and equipment, and systems are being assembled by a variety of fabricators on a routine basis for use in many other industries. Successful utilization requires careful
In this work, a novel method for producing ultrafine tantalum and hafnium carbide fibers using the Forcespinning TM technique via a nonhalide-based sol-gel process was investigated. An optimal solution viscosity range was systematically determined via rheological studies of neat PAN/DMF as a function of fiber formation. Subsequently, ForcespinningsupTM/sup parameters were also systemically ...

Tantalum wire fabrication, processing and machining. Most tantalum wire is made to order by the mill. Tantalum wire fabrication starts with tantalum ingot, that is produced from tantalum scrap or mined tantalum minerals. The ingot size is reduced in a number of steps ending up tantalum wire by wire drawing.The major part of produced tantalum wire is used in tantalum capacitor production.
