Wolfram · Thermal vacuum evaporation — High temperature and maximum resistance

Tungsten Boats

Tungsten boats for resistive thermal vacuum evaporation at very high temperature. Made from rolled W sheet and machined to standardised shapes or custom design. Suitable for evaporation of high-melting-point materials: Pt, Ti, Zr, Ni, Fe, Mo and refractory alloys.

  • Standard sizes 50-150 mm L × 7-30 mm W × 0.5-2 mm t
  • Shapes: flat rectangular, centre trough, dimple (central pocket)
  • W >= 99.95% - higher service temperature than Mo boats
  • Service temperature > 2 400 °C in vacuum < 10^-4 mbar
  • Suitable for Pt, Ti, Zr, Ni, Fe, Mo, Nb and refractory alloys
  • Custom: any geometry to customer CAD drawing
