i prepared powder La0.67Ca0.33MnO3 by 10 h ball milling and 10 h in temperature of 1200. does anybody knows how prepare target from this powder for making thinfilms by sputtering ?
Dear Zahra,
I am not working in this area, but my friend worked on it. You can write to my friend Ranganath. His e-mail ID: [email protected]
Dear Zahra
Before going to answer your question, I want to ask about heat treatment temperature (1200oC), which was mentioned in your question.
Please check the following procedure, which is common for almost all materials.
Processing of pellets/Targets
Step-I PVA preparation (10 wt%)
1. 50 ml distilled water + 5 gms of PVA powder
2. Heated and stirred by spatula/spoon (completely dissolved)
Step-II Pellets/Targets preparation
1. Check the dimensions of your target.
2. By using green density (~60% of theoretical density) of the LSMO material, calculate approximate mass (m grams) for one target.
3. If 10 gms of calcined LSMO powders + 1 ml PVA solution (equal to 0.1 gms PVA powder, 1 wt% to 10 gms powder)
4. LSMO powder and PVA should be properly.
5. Use the proper die set to make the target.
6. Sintered this at optimized or reported sintering temperature.
Thank you so much Dr.Muralist and Ajeet kumar
