Zirconia ceramic crucible performance
Posted by:admin  Date:2013-6-21 3:49:16  Click:4278

Do not know if you know, he is a zirconia crucible to melt in your rare metals, and his temperature performance is very stable, is an ideal high-temperature refractory products. He is also very good thermal stability, purity of 99.9, the highest temperature at 2200 degrees. Jiangsu Province Ceramics Research Institute will give us some more detailed description of zirconia crucible.

Maybe we do not know, in fact, zirconium dioxide is much higher than the melting point of zirconium, he is the best one fire-resistant material. His relatively poor thermal conductivity, but the conductivity is very good, there is also good resist him, even if the temperature to 1900 degrees he would not turn aluminum, platinum and other reaction. So use him to carry on the crucible manufacturing is very good. In enamel and glass which can add zirconia, he can better to resist acid corrosion.

In the zirconia material, we can also add 5% calcium oxide, so that he can rise high temperature degrees and 500 degrees. He must have three times as much heat. We can white zirconia ceramic in which seeped into, so you can make more white and bright ceramic, strength also become large, we can use this to produce high-temperature ceramic insulating ceramic, and his force is relatively well insulated.(picture/text http://www.jiangsuceramics.com/)
