Tantalum Gauze is a product offered by Goodfellow that consists of woven tantalum wire in a gauze form. Tantalum is a refractory metal known for its high melting point, excellent corrosion resistance, and bio-compatibility. The Tantalum Gauze is available in 12 different mesh sizes to suit a variety of filtration and high-temperature applications. Potential uses include filtration of corrosive chemicals, catalyst support in the chemical industry, and high-temperature furnace baskets. It provides options for creating filters, diffusion barriers, and other components resistant to extreme environments.
