Applied Physics Technologies specializes in float zone refining of refractory metals, transition metal carbides, LaB6 and CeBix. We have extensive facilities for growing single crystal rods of these materials. APTech also centerless grinds and in some cases electrochemically etches rods to exacting dimensional specifications.
Single Crystal Refractory Metals and Wire
- Tungsten rod and wire, oriented, single-crystals
- Diameters range from 0.12-mm for etched wire to 2.5-mm for as-refined rods.
- Common orientations include (100), (310), and (111) crystallographic directions on axis.
Single crystal tungsten wire is zone refined, and axially oriented to the specified crystal plane within 2º. Metal impurities are less than 30 parts per million by weight. Wire is centerless ground, then electrochemically etched to the specified diameter, +/-.0003", and cut to the specified length.
