      Hi again,

      Thanks for the fast reply, that must be the problem!

      I was just wondering if either of you could recommend any suppliers of Sintering Beads in the UK?

      Regards,

      I would calibrate the furnace. In addition, CubeX2 should have high temp of 1450.

      I know it is late response for this. But i was just thinking and i believe Jensen is in the uk now. They would have sintering beads.

      Sometimes they need a break-in period to fully stabilize, then you can check the temps and adjust accordingly. It was tested at the factory, but since then it's been bounce around in at least three vehicles and been in at least 3 different (non-vehicular) environments.

      and

      Greetings Earthing! Welcome!

      Hello dude, I just make this sintering curve:

      Ramp 1: 8° C per minute

      High Temp 1: 900° C

      Hold: 0 hr 30 min

      Ramp 2: 3° C per minute

      High Temp 2: 1450° C

      Hold: 2 hr 0 min

      Cooling Reg: Cool to 400° C in 2 hours and then let cool to room temperature naturally.

      In my experience, all zirconia crows dont look good after sintering, you need to stain and glaze it, and then you can get a good product.

      I cant attach the photos because it said "they are too big", send me you email and I can send you a couple if you want.

      Regards
