Alumina coated tungsten boat, dimple 12.7 x 3.2mm

The alumina coated tungsten boat replaces alumina crucibles for some specific applications. Good heat transfer yet has alumina inertness. Evapourant does not wet the alumina: no resistant change of the boat when evaporant melts. Due to the non-wetting characteristic, the evaporant forms a sphere when melted, resulting in a point source.

Specifications:

• 101.6mm L x 12.7mm W, dimple 12.7mm diameter x 3.2mm deep
• Melting point of tungsten boats with coated Al₂O₃ tabs is 3422C
