Question:

We have a high temperature application.  We'd like to use ceramic components in our test chamber.  Can your ceramics withstand about 1200°C continuous in a gas fired furnace?    

Ceramic Specialist:

Yes our high purity ceramics can certainly withstand this temperature without a problem.  We would recommend ramping up relatively slowly to avoid thermal shock.  Thermal shock will occur when the ceramic components increase or reduce temperature too quickly and might cause cracking.  We suggest a ramp rate of approximately 100°C per hour.  In regards to cooling, when it's time to reduce the temperature it's also wise to bring the temperature down slowly.  We suggest reducing the temperature at a rate of 100°C per hour as well.  This will also prevent thermal shock.
