Plasma Process, LLC is producing refractory and noble metal foams for a variety of applications.  The foams are available in various porosities from 30 to 100 PPI (pores per inch) configurations, in Tungsten, Rhenium, Molybdenum, Niobium, Tantalum, Hafnium, Zirconium, Iridium, Ruthenium, Rubidium, and Platinum; as well as alloys such as Iridium-Rhodium and Iridium-Platinum.  The foams have an open cell structure consisting of a regular matrix of connecting ligaments (Figure 1).

Figure 1: a) 60 PPI Iridium Foam disc      
b) SEM image of Iridium foam showing the unit cell.

Surface area of foam samples was measured using BET gas absorption analysis to average 0.450 m²/g for 60 PPI Iridium foam to 0.815 m²/g for 60 PPI Ruthenium foam.  The foams have a high compressive strength, which can be tailored by adjusting the density of the foam and the thickness of the ligaments

 Iridium foams developed by Plasma Process, LLC have been used successfully for the catalytic ignition of AF-M315E and LMP-103S monopropellants in thrusters.  In this application, Iridium foam has operated at very high temperatures of approximately 1850 °C (3362 °F).  The high temperature strength of the foam allowed the foam to operate without the need for a catalyst bed plate required by granular catalysts.  The monolithic structure of the foam increases the durability and service life of the catalyst.

 Because of the varied selection of materials and porosities in which these foams can be produced, as well as Plasma Processes’ ability to tune mechanical and material properties of these foams allows for a there is a wide range of applications for these foams that include catalysts, biomedical and biomaterial applications, anodes in electrochemical processes, among many other industries and uses.
