Tungsten evaporation boats
Thermal vacuum evaporation tungsten/molybdenum/tantalum boat
We can supply evaporation boats manufactured from tungsten, molybdenum, molybdenum-lanthanum (ML), molybdenum-yttrium oxide (MY) or tantalum.Our evaporation boats offer a good level of electrical conductivity and possess low vapor pressures combined with a very high melting point and chemical stability.After powered on, our boats heat the material for evaporation.During this process, the low vapor pressures of our metals ensure that no tungsten, tantalum or molybdenum particles enter the vapor and penetrate the subsequent layer.
1. Straight type
2. Non splash type (boat with wings or cover to minimize splash)
3. Step type (boat with steps between clamping part and tup part)
Surface of boat :Ordinary metal matt surface or electro-polishing bright surface.
Tub shape :
1. Box shape
2. Sphere tub for expensive coating material for gold and silver
3. Flat tub for material with high wettability
4. Oval tub for materials whose melts tend to circulate
5. V tub for material with less wettability
Dimensions of boat:
We provide tailor-made method according to your demands.please tell us which material (molybdenum,tungsten,tantalum)and what is the thickness,length,width,Tub length and Tub depth,then we can help you to solve the problem perfectly.
