Product Introduction
1. Product name: Tungsten Evaporation Boat
Resistance heating is a high-temperature evaporation source. Tungsten has a very high melting point and very little equilibrium vapor pressure. The performance is very stable and as the emission material, and the evaporation sources of various shapes (including filamentary, spiral, Disk-shaped, and boat-shaped sources), among which the boat-shaped evaporation source is what we call "tungsten evaporation boat".

3. Tungsten evaporation boat features:
①High melting point
②Low saturated vapor pressure
③Stable chemical properties
4. Our company and factory:
The tungsten evaporation boat is stamping from the tungsten sheet. When the two ends are electrified and heated, the plating material placed in them is heated to form a molten pool in the boat and evaporates to carry out the coating. There are more than 80 kinds of compounds and metals that can be heated with a tungsten evaporation source. Baoji Magotan Nonferrous Metals Co., Ltd is very mature in the R&D and production technology of the tungsten evaporation boats. And we can design and customize different molybdenum evaporation boats according to customer requirements.
5. Tungsten evaporation boat process:
6. Expand knowledge:
1) Sputtering coating can be divided into:
DC Diode Sputtering: For Conductive Films Only
DC three-pole sputtering: only for conductive films
DC Quadrupole Sputtering: For Conductive Films Only
2) RF sputtering: using RF power supply, can be plated with silicon oxide and aluminum oxide materials
Counter-target sputtering: can increase the deposition rate, and produce magnetic iron, nickel, and other magnetic alloy films
3) Ion beam (IBS) sputtering: uses an ion source to emit ions.
