摘要

Resistance-heated ceramic vaporization boat (10) comprises a longitudinally extending body with a parallel running upper side (1) and a lower side (2) and non-parallel planar side surfaces (3) which enclose an angle of 45[deg]. Preferred Features: A cavity (4) is formed in the upper side. Tension regions are molded to the free end sections and have a height which is not more than the height of the boat.
