Silver as high-tech material
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the increasing role of silver in high-tech applications. It considers existing and anticipated uses, availability, and price trends. In terms of the Atlas of Technological Megatrends it is concerned with the processing of matter (M).
Silver has two roles in society: (i) Physical use. (ii) Store of value.
In 2012 physical supply was 1048 million ounces, made up mainly of mining production of 787 million ounces, and re-used "old silver" of 254 million ounces. Other sources were negligible. On the demand side, 846 ounces were used in "manufacture". This included high-tech applications, conventional industrial use, coins, medallions, and jewelry. The residual - the amount that balances supply and demand - is characterized as: "implied net investment". [The Silver Institute, 2013, Silver Survey.]
Because of its unique physical attributes, silver is used in many high-tech applications: cell phones, computers, TVs, batteries and solar cells. Anticipated future developments include the large-scale use of silver’s anti-microbial features suited for medical applications, water purification and packaging.
However, questions arise concerning availability, and price stability. Silver’s price rose from an approximate average of USD 5.00 an ounce in 2003 to USD 31.00 in 2012. In 2013 the price tended towards the USD 20.00 level.
In evaluating future price and availability, technology explorers should consider the interplay of two trends. First, increasing price pressure caused by growing physical demand for silver as high-tech material. Second, decreasing price pressure, as signaled through the banking sector, and reflecting silver’s status as a store of value.
