Alumina coated tungsten boat, trough 44.5 x 16mm

The alumina coated tungsten boat is a combination of the refractory metal tungsten and an alumina barrier (Al2O3) coating over the tab area. The exposed metal area comprising the bottom of the boat allows the sample to be in good thermal contact with the source. The barrier will tend to help concentrate the heat towards the centre. The alumina barrier will inhibit an evaporant (if used as a sample instead of an aperture) from creeping toward the heat sink or from wetting the entire boat.
