The reason why the muffle furnace does not add the bottom plate of the furnace affects the service life?

Қашан ceramic fiber muffle furnace is used to heat the sample, the bottom plate of the furnace is not added.

Furnace bottom backing plate is also called setter plate and sintered plate. Each muffle furnace is equipped with a furnace bottom backing plate of corresponding size, and all heated samples, including the container carrying the sample, should be placed on the furnace bottom backing plate for heating experiments. The materials of the bottom plate of the furnace are: ceramic, polycrystalline mullite, silicon carbide, etc., according to the temperature of the ceramic fiber muffle furnace, the furnace bottom plate of different materials is equipped.

The use of the furnace bottom backing plate is to avoid heating the sample directly on the ceramic fiber board at the bottom of the furnace, which may cause uneven local stress on the fiber board or excessive local temperature, which may damage the bottom of the furnace.
