I want to deposit YAG (yttrium aluminum garnet) on another YAG substrate. YAG has been known to be deposited by electrophoretic deposition on ITO substrate using a suspension of magnesium nitrate, isopropyl alcohol and deionized water.
You want to deposit on an insulator? How to apply DC on an insulator?
Professor Muralidharan, I am very new to the idea of electrophoretic deposition. I feel that on a very basic level, it is deposition of a material on an electrode by mass movement of solid particles in a liquid medium by application of a field. So pardon me if I don't understand your question. I do want to deposit it on an insulator but I don't understand the next question. In the context of depositing YAG on YAG by electrophoretic deposition, how should i try to make a system if it is at all possible ?
The copper layer would still remain on the substrate in this process, right ? Can it (this copper layer) be removed by any process after the EPD ? Other than Cu which other metals can be used for electroless deposition ?
You may try coating a conducting polymer film, such as Polyptrrole (Ppy) on YAG substrate before EPD. Polypyrrole being organic will burn off subsequenty when you calcine/sinter the deposit. The attached reprint might help.
