Zirconia ultra-high temperature electric furnace uses zirconia as the heating element. Its operating temperature is up to 2000~2200℃ in the oxidation atmosphere. Without protection atmosphere, it can be used continuously for more than 700h above 1900℃ (the maximum temperature can reach 2000℃), and can be used continuously/intermittently between room temperature and 1900℃. It is an excellent new type of high temperature heating element.
