These high-temperature furnaces are ideally suited for sintering bridges and crowns made of translucent zirconia. The special heating elements made of molybdenum disilicide promise very good protection against chemical interaction between the charge and the furnace components.

The bridges and crowns are loaded in ceramic saggars. These high-temperature furnaces are particularly convincing due to their very good price-performance ratio. The furnaces can be individually programmed for all recommended sintering curves by almost all zirconium manufacturers.

Tmax 1650 °C
Furnace chamber with a volume of 1 or 4 liters
High-quality heating elements made of molybdenum disilicide offer very good protection against chemical interaction between charge and heating elements
