In one aspect, evaporator boats are provided which, in some embodiments, exhibit resistance to corrosion and associated performance degradation imparted by exposure to molten metals, including aluminum. An evaporator boat described herein comprises a body and an evaporator surface, the body comprising a boron nitride (BN) component and a TiBcomponent including a solid solution of TiBand one or more elements selected from the group consisting of silicon and metallic elements of Groups IVB-VIIIB of the Periodic Table.

Evaporator boats for metallization installations

Resistance-heated ceramic vaporizer boat () comprising an elongated vaporizer body having an upper side () and a lower side () being parallel to each other, and the vaporizer body having plane lateral side surfaces () being non-parallel to each other, wherein each of said lateral side surfaces () is inclined by an angle of 45&#xb0; with respect to the upper side (). Preferably, the end portions at the longitudinal ends of the vaporizer body are reduced, at the lower side () thereof, to a predetermined partial thickness (t), whereby a cavity at the upper side () of the vaporizer body can be omitted.
