_ Program 2 [P2] – fast
▪ Quick-sintering program for zirconium oxides -
single units.
▪ Quick-sintering program only for single units -
Max. furnace filling load is one sintering bowl;
otherwise, sufficient through-sintering of the
objects cannot be achieved.

_ Program 3 [P3] – slow
▪ Sintering program with long-term cooling for
zirconium oxides.
▪ Sintering program with dwell phase at 900 °C
and defined cooling. Particularly for large and
massive frames on which the connected
remaining blank is also sintered.

_ Program 4 [P4] – default
▪ Parameter freely assignable
▪ The program is preset to 1500 °C, 2 hours
dwell time and a heating rate of 10 °C/min (not
material-specific).

When the maximal temperature of
1530 °C is set, a maximal heating rate of
8 °C/min is recommended, in order to pre-
vent ageing of the heating rods. Continu-
ous operation of the furnace at 1530 °C
leads to premature ageing and glazing of
the heating rods!
