Tantalum Evaporation Boats

1. Product name: Tantalum evaporation boats

Tantalum evaporation boats have a lot of excellent properties such as high melting point, low vapor pressure, good cold working performance, high chemical stability, and strong resistance to liquid metal corrosion. The most impressive about tantalum evaporation boats is their high corrosion resistance.

2. If the tantalum evaporation boats are used correctly, they can not only prolong their service life but also bring us greater economic benefits! To exert the performance of the tantalum evaporation boat and achieve a long service life, please pay attention to the following operating points:

(1) The two rows of fixtures should be kept aligned, and the surface should be kept smooth;

(2) Graphite paper should be used on the end face or side to ensure good electrical contact and heat conduction;

(3) When the new boat is heated for the first time, put a piece of aluminum wire in the center of the groove to facilitate and accurately determine the temperature of the evaporation boat (note: this method cannot be used when using a triangular boat without a groove);

(4) The contact point of the aluminum wire should be located at 1/3 to half of the length of the boat;

(5) The heating of the new boat should not be too fast, so as not to affect the deflation;

(6) When the new boat is used for the first time, the aluminum feeding speed should be gradually increased from about 75% of normal, and the power should be gradually reduced to achieve a larger liquid aluminum spreading area.

3. Tantalum evaporation boat specifications:

Tantalum evaporation boats can be designed and customized according to customer requirements.

4. Features of Tantalum evaporation boat:

1) high melting point

2) low saturated vapor pressure

3) stable chemical properties

5. Our company and factory:

When the tungsten evaporation boats are heated to the evaporation temperature, they will become brittle due to heating and crystallization; the molybdenum evaporation boat will become brittle due to different purity, some will become brittle, and others will not become brittle, and tantalum evaporation boat will not become brittle. Baoji Magotan Nonferrous Metals Co., Ltd is very mature in the R&D and production technology of tantalum evaporation boats. And we can design and customize different tantalum evaporation boats according to customer requirements.

6. Commonly used vacuum coating machine (coating method)

1)Resistance evaporation coating machine (vertical double door, vertical bell jar, horizontal drum, horizontal winding).

2)Electron beam evaporation coating machine (box-type single door, high precision).

3)Ion beam assisted evaporation coating machine (box type single door, electron beam, high precision, good compactness)

4)Magnetron sputtering coating machine (vertical single and double doors, horizontal).
