Depending on requirement, the frames can be partially or com-
pletely coloured with Ceramill Liquid dye solutions (see processing
instructions for Ceramill Liquid dye solutions).
Final sintering
▷
Place the Ceramill ZI frames for sintering into the sintering bowl
(178360) filled with sintering pearls (178311).
▷
To ensure proper support, place the frames with slight pressure
onto the sintering pearls.
▷
Perform the final sintering of the frames according to the following
program:
▪
Heat-up phase: Room temperature to final temperature 1450
°C
;
heating rate 5 - 10 K/min
▪
Dwell time at final temperature: 2 hrs
▪
Cooling phase: Final temperature 1450
°C
to room temperature
(at least < 200 °C); approx. 5 K/min (approx. 5 hours)
The Ceramill Therm high-temperature furnace (178300/
178350) or another high-quality and suitable furnace is rec-
ommended for the sintering (please also refer to the operat-
ing instructions of the respective sintering furnace).
NOTE:
▷
Pay attention that no pearls are jammed in the interdental spaces
or located in the crown cavities!
