Fig. 1. The H. C. Starck pyrometallurgical upgrading process of Ta—Nb-containing tin slags where the soHd vertical bars represent electrodes. The product of (a) electrothermic reduction of Sn slag goes to (b) oxidation of Fe alloy 20—60 Ta + Nb and then to (c) electrothermic reduction of oxidized Fe ahoy.

For electrode manufacturing, powder of Ni(OH)2 was used, produced by H.C.Starck, USA. The product has mean particle size of d50 6p.n1. It was mixed with conductive additive, such as, for instance, refined graphite powder.

The fuel cell analyzed in the present section is a disk-shaped anode-supported SOFC, currently produced by H.C. Starck/InDEC B.V As illustrated in Figure 4.1 [1], the anode material is a cermet of nickel oxide doped with yttrium stablilized zir-conia (NiO/8YSZ). The cathode is composed of two layers one made of 8YSZ with strontium-doped LaMnC>3 (8YSZ/LSM) and one of LSM. The electrolyte consists of a dense 8YSZ material.

Table 14.2 gives an overview of various pads and slurries, suitable for microfabrication. The compiled list is based on the information obtained from some consumable manufacturers as well as the experience accumulated at the author s lab as of Spring 2006. Besides the large suppliers like Cabot Microelectronics, Fujimi, and Rohm Haas, smaller companies are concentrating on custom-specific developments such as Kemesys in France as well as suppliers of abrasives or dispersions, for example, Degussa AG or H.C. Starck, both from Germany. Links to some of these suppliers are provided in the reference section [19].

The ZrB2-SiCp (ZS) composite were fabricated by hot pressing in a graphite die at Materials and Machines, Inc, Tucson, AZ, and contained 20 v/o SiC particles. Cu-clad-Mo plates, obtained from H.C. Starck, Inc, Newton, MA, had Cu-to-Mo-to-Cu layer thickness ratio of 13%-74%-13%. The commercial brazes, Palco, Palni, Cusil-ABA and Ticusil were obtained in foil form (thickness 50 pm) from Moigan Advanced Ceramics. The compositions, liquidus and solidus temperatures, and selected properties of the braze alloys are given in Table 1. 

For these experiments H.C. Starck Ceramics has manufactured and provided a full ceramic auger (Fig. 8) consisting of two auger segments from silicon carbide (SSiC) and a new TZP Zr02-lfont auger. The segments were adhered onto a stepped steel rod, like described in Fig. 4.
