High-Temperature Furnace with SiC Rod Heating
for Sintering Zirconia up to 1550 °C

Designed as a table-top model with SiC heating rods, this comparably inexpensive hightemperature furnace offers numerous advantages when sintering non-translucent zirconia with
an operating temperature of up to 1500 °C. Compared to other models, however, the costs for
changing the heating elements are higher.The large heating chamber and fast heat-up times
make this model a good choice for CAD/CAM machining of zirconia. The controller of the furnace
is freely programmable for the individual sintering of the zirconia material. The high-temperature
furnace is also designed for connection to the single-phase power grid.
