High-Temperature Furnaces up to 1650 ยฐC for Sintering Translucent Zirconia

hese 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.
