Manufacturing Chromium Powder for Sputter Targets
October 4, 2018 / by The EXOTECH Team / Uncategorized
A sputtering target is used to make thin films through a process called sputter deposition. The process takes a solid material, breaks it down into small particles using gaseous ions, and then sprays it onto another material. This process is often used to make computer chips and semiconductors, and it often uses Chromium powder. The […]

Battery Charging Could Become Faster Thanks to Cheap Materials
October 1, 2018 / by The EXOTECH Team / Uncategorized
Scientists have recently determined that a new group of cheap materials may actually hold the key to faster battery charging. If further testing shows this to be true, it’s possible that smartphones and other devices could go from very low battery to completely full in only a few minutes. The implications for these materials go […]

BEING A CONFLICT FREE TANTALUM SCRAP METAL PROCESSOR
April 28, 2018 / by The EXOTECH Team / Uncategorized
The demands of the Dodd-Frank Act and the mandates of the EICC/GeSi program (collectively called the protocols as stated in http://www.resolv.org/wp-content/uploads/2012/04/Smelter-Intro-Training_Final1_04_07_2012.pdf ) create many ‘grey’ areas for the scrap metal processor of ‘The 3 T’s and Gold’. The 3 T’s are Tin, Tungsten, and Tantalum. The EICC Code of Conduct is spelled out in http://www.responsiblebusiness.org/media/docs/EICCCodeofConduct5_English.pdf […]

The Big Tantalum Recovery
March 30, 2018 / by The EXOTECH Team / Uncategorized
One of Mark Gussack’s fondest stories that he tells at Exotech, is of the ingenuity to recover Tantalum from a difficult source. The story goes back over 20 years ago. In the late 1970’s, DuPont had built a new facility to produce Carbon Tetrachloride, a common cleaning fluid at the time. Shortly after the […]

Manufacturing High Purity Chromium Powder at Exotech
February 13, 2018 / by The EXOTECH Team / Uncategorized
The first step in converting Chrome ore into Electrolytic Chromium Metal is to dissolve Chrome ore in a solution suitable for the electrolytic process. The two most common types of solution are Chrome Alum Sulfate and Chromic Acid. The first is what is known as the trivalent process and the second is the hexavalent process. […]

Exotech’s Five Basic Activity Areas
February 12, 2018 / by The EXOTECH Team / Uncategorized
Exotech manufactures high purity Chromium powder for the sputter target, electrical contact and thermal spray industries. In addition to primary virgin Chromium, we purchase used Chromium sputter targets. Primary Chromium is purchased in the form of flakes, ‘eggs’ and chunks. We process the virgin Chromium metal and scrap Chromium targets into powder by chemical and […]

THE IMPORTANCE OF SELLING USED TANTALUM SPUTTER TARGETS INTO THE SCRAP METAL MARKET
February 12, 2018 / by The EXOTECH Team / Uncategorized
INDUSTRY NEED FOR USED TANTALUM TARGETS Selling used (scrap) Tantalum sputter targets into the scrap metal market for recycling creates an important source of Tantalum metal for the needs of industry. If this supply were not available, industry would have to purchase only virgin Tantalum from the Tantalum metal producers, thus eliminating competition from an […]

The World of Tungsten
February 9, 2018 / by The EXOTECH Team / Uncategorized
Tungsten, while a relatively rare and exotic metal, is used in many products that we encounter every day. Tungsten is both very heavy and very hard. Most of its applications stem from those two properties. It is also reasonably priced compared to the price of other rare and exotic metals. Its price is substantially below […]
