HAFNIUM

Hafnium products are characterised by low content of impurities, including zirconium (0.1-0.5%).
Hafnium is used in metallurgy of heat-resistant alloys, production of plasmatrons, special optics, microelectronics, as well as in the nuclear power industry.

The product range includes four main types of powders, differing in particle size and apparent density. They are produced by electrochemical precipitation from aqueous solutions of metal salts with subsequent drying and heat treatment in a reducing environment in accordance with the requirements of technical specifications: 
 • TU 1793-001-07622839-2002, Grades PNE-1, PNE-1 Luxe 
 • TU 1793-005-07622839-2003, Grade A-2
 • TU 1793-007-07622839-2004, Grade AE-II-BT

Zirconium products are widely used in the petroleum, chemical, and nuclear power industries, as well as in mechanical engineering.
The main difference of zirconium alloys used outside of nuclear power industry is the increased hafnium content (no more than 4.5%), in comparison with nuclear-grade zirconium (no more than 0.05% hafnium).

Tantalum has similar physical and chemical properties to niobium. Key properties of tantalum include high heat transfer coefficient and gas absorption capacity, heat resistance, refractory quality, chemical and corrosion resistance, ductility, and high biocompatibility.
Tantalum is widely used in aircraft construction, space technology and chemical production, in the manufacture of high-accuracy gauges of weights and measures. Properties of tantalum are used in tele- and cellular communication devices and electronic tubes.
Depending on the customer's requirements, the monitoring of all stages of production before the delivery of finished goods, made of metallic tantalum, can be performed with the participation of representatives of various departments.
