Plane Molybdenum Target
Molybdenum sputtering target according to the shape can be divided into a plane molybdenum target, multi-arc molybdenum target, rotating molybdenum target and so on. Plane molybdenum target mainly refers to circular target and rectangular target having a certain thickness. The molybdenum target usually connects with the sputtering equipment by threaded connection.
Plane molybdenum target production processes are as follows: 1. Put the raw material into rubber mold set to obtain solid core silty molybdenum plate blank; 2. Then to press by cold isostatic pressing with pressure 300-400Mpa, after 8 minutes can obtain solid slab; 3. To put the solid slab into intermediate frequency sintering furnace, passing through hydrogen, heating to 2300 ℃, heating time is 28 hours. After water circulation cooling for 10 hours, cooled to room temperature can obtain blank; 4. To heat the blank to 1500 ℃, heating time is 2 hours, after hot rolling mill rolling make the shape up; 5. After machining can obtain plane molybdenum target.
