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

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!
