Nabertherm LHT 03/17 D Sintering Oven

High-Temperature Furnaces up to 1650 °C for Sintering Translucent Zirconia

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 the best possible 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 excellent price-performance ratio. The furnaces can be individually programmed for all recommended sintering curves by almost all zirconium manufacturers.
