What You Need to Know about Recycling Used Magnetron Sputtering Targets

We’ve written about sputtering targets many times before on this blog, including this great explanation of how sputtering targets work. They can contain valuable quantities of precious metals, even after they have outlived their useful life in your coating operations.

Shown: scrap sputtering targets, which can contain gold, silver, platinum, palladium and rhodium, and can be refined and recycled by Specialty Metals.

But what about magnetron sputtering targets? Do they, like gold-bearing sputtering targets, contain valuable quantities of recyclable precious metals? Let’s take a closer look.

What is Magnetron Sputtering?

The first impulse magnetron sputtering (HPIMS) machines were introduced to the market in 2006. They are high-powered sputtering machines that are now widely used in many coating applications for one simple reason: They can apply very dense layers of thin films onto a variety of surfaces, most often ceramics, glass and plastic.

  • Magnetron technology is most often used to apply coatings to:
  • Automotive headlight housings and other reflective surfaces
  • Architectural glass
  • DVDs and CDs
  • Photovoltaic cells
  • Solar panels
  • Superconductors
  • Flat panel displays
  • Lighting surfaces
  • Medical testing devices

Magnetron sputtering machines are also sometimes used to “etch” or pre-treat surfaces that will then be coated using regular sputtering technology.

Here’s a very informative video about magnetron sputtering that was produced by Norfolk State University. If you watch until the end, you’ll see that the HPIMS equipment has been used to coat a glass slide with a thin conductive film.

What Metals Do Used Magnetron Targets Contain?

Used magnetron sputtering targets that were used to apply reflective coatings on glass most often contain quantities of silver and metal oxides, including zinc oxide, tin oxide, or titanium oxide. Yet it is worth remembering that used sputtering targets contain more than just the metals that they were used to deposit – they can contain other metals too, such as thin layers of silver or other metals that were used to bond the targets onto their substrates. If you have used sputtering magnetron targets and would like to know whether they can be profitably recycled, call the best precious metals refiners, Specialty Metals Smelters and Refiners, at 800-426-2344. We’ll be happy to help you recoup maximum dollars from the precious metals they may contain.
