Ceramic fiber board is a very good refractory material with very strong performance, so generally speaking, it will not suddenly crack during use. Therefore, if the ceramic fiber board suddenly cracks when using it, it means that the material quality of the ceramic fiber board is not up to standard, there are certain problems, and it cannot continue to be used. So having said that, what is the reason that causes ceramic fiber boards to suddenly crack during use?
1. During the heat treatment of ceramic fiber boards, due to excessive temperature, the carbides are completely dissolved and the grains become coarse; at the same time, insufficient tempering results in increased residual stress and brittleness;

2. When grinding ceramic fiber boards, due to excessive feed, insufficient cooling results in large thermal stress and structural stress on the surface. Superimposed residual stress can easily cause grinding cracks.

3. Improper use of ceramic fiber boards, causing external force to cause the board to suddenly crack during use.
4.Chemical Reactions: Certain chemicals or gases in the environment can react with the ceramic fiber board, leading to the degradation of the material and the formation of cracks. It's important to choose the right type of ceramic fiber board for specific chemical environments.
5.Inadequate Support or Fixing: If the board is not adequately supported or fixed in place, it can flex or sag under its own weight or under external loads. This flexing can create stress points and lead to cracks.
Therefore, whether you are buying a ceramic fiber board or before using it, you must do relevant inspections to ensure that there is no problem with the quality of the ceramic fiber board you purchased, and then you can use it in the correct way, so that it can be used in a long time. To a large extent, the ceramic fiber board will be prevented from sudden cracking during use.
