The Function and Advantages of Zirconia Special Ceramic Crucibles

1. The zirconia special ceramic crucible has good high-temperature stability and is an ideal experimental high-temperature refractory system. The purity of the zirconia special ceramic crucible reaches 99.9%, the density is 6.00%, and the maximum operating temperature is 2200 degrees. It is mainly used for melting precious metals and has good thermal stability. The main purpose is to melt precious and rare metals.

2. The melting point of zirconia ceramic ball milling tank is higher than that of zirconium, reaching 2700 ℃, making it one of the materials with refractory properties in nature.

3. The thermal conductivity of zirconia special ceramic crucibles is poor, but they have strong conductivity and corrosion resistance. Even if heated to over 1900 degrees Celsius, zirconia crucibles will not react with molten metals such as aluminum, iron, nickel, platinum, silicates, and acidic slag.

4. Zirconia special ceramic crucibles can be used to manufacture zirconia special ceramic crucibles, zirconia ceramic structural components, refractory pipes, heat-resistant glass, and heat-resistant enamel for melting precious metals. Adding zirconia to enamel and glass can enhance their resistance to acid and alkali corrosion.

5. The volume of zirconia special ceramic crucible lined with zirconia ceramics will not increase significantly after heating, and the temperature change has little impact on it. The zirconia special ceramic crucible will not cause cracks due to thermal expansion and contraction, which can greatly extend the service life of the zirconia special ceramic crucible.

6. Using zirconia as a refractory material and adding 5% calcium oxide as a stabilizer, its heat resistance temperature is 500 degrees higher than that of alumina, and its insulation capacity is three times higher than before.

7. Adding white zirconia to ceramics can make them cleaner, brighter, more heat-resistant, and have increased strength. Using this type of ceramic to make high-temperature insulating porcelain bottles has strong insulation ability and a small coefficient of expansion.
