Tungsten Boat - High Purity 99.9% Tungsten Material, Efficient Evaporation Coating Process, Ideal For Vacuum Chamber Applications

We are engaged in manufacturing and exporting excellent quality Tungsten Boat to our valuable clients. Evaporation coating works put membrane material in vacuum coating indoor, by evaporation source heating evaporation, when the evaporation molecular mean free path is greater than the linear dimensions of the vacuum coating chamber, the steam of atoms and molecules escape from the surface of the evaporation source, little impact of other molecules or atoms and the obstacles, can directly reach the plating surface of the substrate, due to the low substrate temperature, then condensation and film.
