Nabertherm furnace LHTCT 01/16

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

These high-temperature furnaces are perfectly suited for sintering of translucent zirconia units. The
special molybdenum disilicide heating elements offer the best possible protection against chemical
interaction between charge and heating elements.
The zirconia units are positioned in ceramic saggars. Up to three saggars can be stacked into the
high-temperature furnace.


Designed as a table-top model with SiC heating rods, this comparably inexpensive high-temperature 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.
