What Are Sputtering Targets Used For?

First discovered in 1852 and developed as a thin film deposition technique in 1920, sputtering targets are a physical vapor deposition mechanism—an old process, but with many uses in modern technology and manufacturing. The process starts by feeding a substrate (or other item to be coated) into a vacuum chamber containing two magnets. After introducing […]

Facts about Tantalum: Applications & Uses

Tantalum (Ta) is an unsung hero in modern metallurgy. First discovered by the Swedish chemist Anders Ekeberg in 1802, this versatile metal has become essential to numerous industries over the years. Raw tantalum rarely occurs in nature. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan). Once extracted, pure tantalum […]

The Value of Tantalum Experience

Tantalum is expensive. For most users of Tantalum, it is likely the most expensive material they buy. It’s for that reason that so many companies source their material from smaller mills overseas to avoid paying the higher prices charged by the big American mills. But with so many companies selling tantalum, how can you tell […]
