How do ceramic fibers react with acids and bases at high temperatures?

Ceramic fibers generally exhibit resistance to acids and bases at high temperatures, but their reactivity can vary depending on the specific composition of the fibers and the chemicals involved. Most ceramic fibers, such as those made from alumina or silica, are stable in acidic environments and can withstand exposure to acids without significant degradation. However, they may react with strong bases, particularly at elevated temperatures, leading to potential corrosion or structural changes. The reaction can result in the formation of new compounds or the dissolution of the fiber material, which can affect its mechanical properties and performance. It's important to consider the specific fiber material and the conditions of exposure when assessing their interaction with acids and bases at high temperatures.
