99.95% pure tungsten, molybdenum, and tantalum resistive thermal evaporation boats, baffled box sources, and stranded tungsten wire baskets/coils.
Resistive thermal evaporation remains the simplest, lowest-radiation-damage PVD technique for contacts, organic semiconductors, halide perovskites, chalcogenides, and metal films. Stamped and precision-formed from ductile vacuum-grade 99.95% tungsten, molybdenum, and tantalum strip (0.127 mm / 0.005" to 0.50 mm / 0.020" thick), our resistive boats deliver predictable current-temperature profiles across low-voltage high-current clamping posts.
We also supply multi-strand twisted tungsten wire baskets (for Al wetting or crucible heating), alumina-coated tungsten boats (preventing molten metal alloying with bare W), and baffled chimney box boats eliminating spitting for SiO, ZnS, and organic/perovskite precursors.
