    Zirconia Sintering Furnace
    This Zirconia sintering furnaces is perfectly suited for sintering zirconia crown. The special high purity Molybdenum disilicide heating elements offer best possible protection against chemical interaction between charge and heating elements. The zirconia crown are positioned in ceramic sintering trays. Up to three sintering trays can be stacked into the furnace.

    1. Max temperature: 1700℃
    2. Working temperature: 1600℃
    3. Automatic program for heating, platform moving. It's very convenient for dental crown firing.
    4. Touch screen panel which can store 500pcs different programs
    5. 30 programmable segments for precise control.
    6. Built in protection for over-heated and broken Thermal couple.
    7. 6pcs high purity MoSi2 heating element can achieve 30℃/min fast heating rate. 
    8. 1 year limited warranty (Consumable parts such as thermocouple, o-rings and heating elements are not covered by the warranty, please order the replacements at related products below.)
