Tungsten boats
Evaporators of this type are the best option for use in the
metallurgical industry, because because of the particularly
refractoriness of tungsten, products made from it are able to withstand
temperatures up to 3000 ° C.
In addition, they are practically immune to oxidative reactions, are
characterized by high resistance to aggressive media and damage during
heating.
Used for deposition of films in vacuum. The principle of operation of
this device is quite simple. The sprayed substance is placed directly in
the evaporator, which during heating and evaporation is deposited on the
desired surface.
As the simplest tungsten sheet evaporator, a tungsten product is usually
used, visually representing a thin plate with a depression of the
required shape.
The parameters of the sheet itself and the recesses are set depending on
their operational need.
In addition, tungsten boats or crucibles obtained from metal sheets by
riveting (bending) or by powder pressing with further mechanical
processing are often used as evaporators of this type.
They are usually used in cases where the evaporated substance has
insufficient wettability (for example, granules or powder) or there are
some other reasons that do not allow the use of a wire evaporator.
Tungsten boats are used in various industrial sectors, most often in
metallurgy, due to the high temperatures that they can withstand.
Used in glass melting and reduction of metal oxides, sintering and
annealing in the vacuum industry, etc.
In addition, it is worth noting that due to the peculiarities of its
design, this type of evaporator allows you to evaporate a larger amount
of substance than wire, moreover, they are more inertial, and therefore
in most cases it is preferable to use.
