Exploding wire phenomena; Metals--Heat treatment
The utility of exploding wire techniques as a method for synthesis of various metal nitrides has been investigated. The metals exploded were titanium, zirconium, aluminum, tantalum, magnesium, platinum, rhodium, copper, zinc, cadmium, iron and nickel. The nitrogen source was ammonia, gaseous and liquid nitrogen, or mixtures of nitrogen and hydrogen. The nitrides of titanium, aluminum, zirconium, tantalum and magnesium were successfully prepared in yields ranging from 6% for magnesium nitride to 53% for titanium nitride. The energy for the synthesis was provided by a large bank of capacitors charged to 9,000 volts. The samples were analyzed using the Kjeldahl method for determining bonded nitrogen. Structural determination using x-ray diffraction was also employed. The thermodynamic properties of known nitrides are discussed and attempts are made to estimate thermodynamic properties of unknown nitrides. An explanation of the results obtained in the synthesis are given in terms of a thermodynamic approach.
