n Advantages:

1. Recrystallized silicon carbide has a high melting point and thermal stability, which can be used for a long time in a high temperature environment and is not prone to deformation and fracture.

2.Silicon carbide burner has good resistance to chemical corrosion and can resist the erosion of corrosive substances such as acid, alkali and salt.

3.Resic burner protective sleeve has good heat conductivity and can quickly transfer heat to the device, improving heat transfer efficiency.
