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?
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.
