Crucible is a bowl or box of different sizes and shapes. It is made of refractory clay baked at high temperature and is usually used as one of the most important kiln tools for loading and firing porcelain. During the firing process, if porcelain is fired directly on the fire, it is easy to crack or break, and there will be a large number of defective products. The use of silicon carbide crucibles, loading all the porcelain blanks into the crucible before firing, can not only avoid damage or contamination of the blanks and glazes caused by certain elements such as gas or other substances, but also ensure the firing quality. Refractory crucibles have good thermal conductivity and thermal stability. The use of refractory crucibles can increase the loading capacity and avoid bonding between ceramics.
The shape and size of silicon carbide crucibles depends on the objects loaded. As a tool for loading and firing porcelain, it can work in one furnace with one blank or in one furnace with multiple blanks, effectively utilizing the kiln space, increasing output, and reducing power consumption.
Advantages of silicon carbide crucible:
-Adding sagger to ceramics can easily increase production
-Ensure the thermal conductivity and thermal stability of ceramics.
-No adhesion, no pollution to porcelain
-Silicon carbide crucible can be shaped according to the firing object, which is more suitable for loading and firing.
-Can be used to protect glaze from harmful gases or substances.
