FYI. Enter the world of the Ta end user: Cabot Performance Materials is a world leader in the technology and production of tantalum and niobium products for the electronics, aerospace and chemical processing industries (http://www.cabot-corp.com/cpm) In addition, Cabot manufactures cesium, rubidium, tellurium, and germanium products for various chemical, electronic and telecommunications applications. Our largest end-use market is the electronics industry. Cabot's tantalum powder and wire are used to make high-reliability tantalum capacitors for cellular phones, computers, pagers, and numerous automotive and consumer electronic devices. Cabot also produces high quality tantalum and niobium for thin film deposition in semi-conductor wafer fabrication and other sputtering applications. Q1. Where is Ta found? With no mineable Ta ore left at Tanco, I guess we have a shot at the titles Tanco still holds ... according to this site: cabot-corp.com Q2.How are Ta powders produced from ore? cabot-corp.com Q3 How is a tantalum capacitor produced? cabot-corp.com H.C. Starck Inc. in Newton, Massachusetts/USA (http://www.hcstarckus.com) produces tantalum capacitor grade powder and tantalum wire and is specialized in production of tantalum mill products (sheet, foil, tubing, wire) for application in the chemical industry. The company employs some 330 people in Newton. For new applications (eg. lithium tantalate and niobate are used to produce the surface acoustic wave filter in the phone's antenna and the microwave filter on the circuit board, while tantalum metal powder and wire are components of the capacitors (http://www.hcstarck.com/aktuell/f_aktuell_e2.htm). KEMET's product line includes tantalum and ceramic, leaded and surface-mount capacitors (http://www.kemet.com/kemet/web/homepage/kechome.nsf/vabypagename/products). Our capacitors are fundamental elements used in every type of electronic equipment, including computers, telecommunication, automotive electronics, military electronics, medical electronics, and consumer electronics. Production is measured in the billions of pieces per year.
