Hi im making some YBCO, I know the formula and have the materials, I just

need some more info on the sintering process.

Thanks

A temperature of 950 Celsius seems to be ok, the sintering time depends on what stage of the process you do it in. Here's one process:

Here's a process that uses hydroxide rather than oxide (not sure if it will yield such a high-purity product but at least it circumvents the use of an external oxygen source):

Good luck! This is really something I wish to do myself as well if/when I buy a tube furnace. While this isn't the easiest synthesis to do at home it's certainly easy compared to other high-temp superconductor materials.
