Zirconium and hafnium are corrosion-resistant metals that are grouped in the same family as titanium on the periodic table. The two elements commonly occur in oxide and silicate minerals and have significant economic importance in everything from ink, ceramics and golf shoes to nuclear fuel rods.

Thallium is known as a poison, its use initially suspected in the recent death of a Russian spy, but it has a variety of more important applications in everything from medical imaging to wireless communications.

Ammonia was produced by 15 companies at 25 plants in 16 states in the United States during 2006.

Data sheets contain information on the domestic industry structure, Government programs, tariffs, and 5-year salient statistics for over 90 individual minerals and materials.

Lithium, the lightest metallic element, is silvery, white and soft, and highly reactive. It is used most frequently in chemical compounds or traded as mineral concentrates. Its thermal properties make it an ideal component in thermal shock-resistant ceramics, and its electrochemical properties make it an ideal material for several types of batteries.
