 | The Paumanok Group: Market Research For The Global Passive Component Industry
|
| | http://www.paumanokgroup.com/pages/capacitors/tantalum/rawmaterials.htm
Paumanok is the leading supplier of market research products and services to the global passive electronic components industry. From off-the-shelf market research reports to customized research projects to technical consulting services, Paumanok offers data on the current and future states of the world markets for passive electronic components.
SUMMARY: This analysis focuses specifically on the world market for raw materials consumed by the tantalum capacitor industry. After an overview of tantalum ore geology and properties, the report presents the volume of ore consumed worldwide for powder/anode, mill product, ingot metal, TaC and Ta2O5/K2TaF7. Primary and secondary mining operations are discussed, including Gwalia/Greenbushes, Pan West/Wodinga, Yinchun and others. New prospecting for ore sources is addressed, including operations in Mozambique, Bolivia and Brazil. The ore supply chain to the tantalum capacitor industry is also described, as are capacitor-grade tantalum metal powder manufacturing techniques such as dissolution, filtration and reduction. The report continues with a discussion of the developments in capacitance value per gram of capacitor-grade tantalum metal powder since 1960 and the corresponding impact on volumetric efficiency of SMD tantalum chip capacitors. The study also chronicles trends in average prices per pound of ore, powder and wire as well as potential effects of Chinese powders on future pricing. Value and volume of consumption of tantalum metal powder are analyzed based on CV/g value, SMD case size and end-use market segments affecting demand. The study includes the consumption volume of capacitor-grade powder and wire by world region and top tantalum capacitor production plant by country. Sales and market shares in the supply of capacitor-grade tantalum metal powder are provided, and forecasts to 2002 for the global consumption of metal powder are included. Companies discussed in this report are Cabot Performance Materials, H.C. Starck-Goslar, H.C. Starck-Newton, H.C. Starck/VTech, H.C. Starck-Thailand, Gwalia Mines, Showa-Cabot Supermetals and Ningxia Non-Ferrous Metals. |

This report from Roskill analyses the key trends, issues and developments in the market.
Summary:Global demand for tantalum has increased strongly since the mid-1990s, exhibiting annual growth of 24%py, to reach a total of over 2,600t Ta2O5 in 2001. This growth in demand has been due largely to the use of tantalum capacitors in small portable electronic components such as laptop computers, video cameras, games consoles and, most importantly, mobile phones. There are a number of new markets for tantalum capacitors that will maintain the growth in demand for tantalum, the most important being under-hood applications in automobiles. Growth in tantalum demand in capacitors is expected to average 9-10% py through to 2005. Other new markets for tantalum have been developed: tantalum oxides are finding use in electronics applications, including computer memory chips and processors. These have the potential to be major consumers of tantalum in the future, although the amount of tantalum used per unit is very small. |

The following document is the final report of the Panel of Experts on the Illegal Exploitation of Natural Resources and Other Forms of Wealth of the Democratic Republic of the Congo. The report outlines a number of issues which surround the extraction of tantalum and niobium from the DRC.
Its content has come under harsh criticism from certain members of industry who have been cited as participating in the illegal exploitation. |

SUMMARY:Columbium and niobium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Columbium in the form of ferrocolumbium is used worldwide, mostly as an alloying element in steels and in superalloys. Appreciable amounts of columbium in the form of high-purity ferrocolumbium and nickel columbium are used in nickel-, cobalt-, and iron-base superalloys for such applications as jet engine components, rocket subassemblies, and heat-resisting and combustion equipment.
Tantalum (Ta) is ductile, easily fabricated, highly resistant to corrosion by acids, and a good conductor of heat and electricity and has a high melting point. The major use for tantalum, as tantalum metal powder, is in the production of electronic components, mainly tantalum capacitors. Major end uses for tantalum capacitors include portable telephones, pagers, personal computers, and automotive electronics. Alloyed with other metals, tantalum is also used in making carbide tools for metalworking equipment and in the production of superalloys for jet engine components.
The United States does not have a columbium or tantalum mining industry because resources are of low grade, and the United States must import all of its columbium and tantalum source materials for processing. Brazil and Canada are the major producers of columbium mineral concentrates, and Australia, Brazil, and Canada are the major producers of tantalum mineral concentrates. |

This report describes the flow of tantalum in the United States in 1998 with emphasis on the extent to which tantalum was recycled/reused. Tantalum was mostly recycled from new scrap that was generated during the manufacture of tantalum-related electronic components and new and old scrap products of tantalum-containing cemented carbides and superalloys. In 1998, about 210 metric tons of tantalum was recycled/reused, with about 43% derived from old scrap. The tantalum recycling rate was calculated to be 21%, and tantalum scrap recycling efficiency, 35%. |
