Zirconia castable cement

Application of zirconia castable ceramic cement.

Rescor® Castable Ceramics are available in 6 refractory compositions offering the ultimate selection of ceramics to the materials engineer. Now, an unlimited number of high temperature applications, requiring custom ceramic shapes, can be easily solved. Just mix the ceramic powders with their liquid activators and pour into any non-absorbent moulds.

Rescor® Castable Ceramics harden overnight to produce highly detailed ceramics, usable to 4000°C. They offer excellent resistance to high temperature, thermal shock, molten metals, oxidizing and reducing atmospheres, erosion, most acids and alkalise.

Rescor® 760 is resistant to a temperature of 2200°C. It is the cement with the highest temperature resistance of our entire range. It also has a very good resistance to chemical attack. This cement becomes electrically conductive when the temperature exceeds 900°C.
