Chemistry of Tantalum and Niobium Fluoride Compounds book cover

Chemistry of Tantalum and Niobium Fluoride Compounds

Electronic, optical, mechanical and medical appliances are just a few examples of modern applications that use tantalum and niobium. In Chemistry of Tantalum and Niobium Fluoride Compounds, the author draws on thirty years' experience to produce the first ever monograph to systemize and summarize the data available on tantalum and niobium fluoride compounds. This comprehensive reference source offers a rich variety of study methodology and is invaluable to researchers examining the chemistry of fluorides, as well as teachers and students in chemistry and metallurgy.

Audience
Tantalum and niobium producers; researchers studying the chemistry of fluorides, teachers and students in chemistry and metallurgy
