Description
These high-temperature furnaces are perfectly suited for sintering of translucent zirconia units. The special molybdenum discilicide heating elements offer 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.
