This paper will deeply discuss the manufacturing process of silicon nitride ceramic electric heating elements, introduce its importance in industrial applications, and analyze the key technologies in its manufacturing process. First of all, we need to understand the material properties of silicon nitride ceramic electric heating elements. Silicon nitride is an inorganic material with high thermal conductivity and excellent thermal shock resistance. This enables the silicon nitride ceramic electric heating element to work stably in a high temperature environment, and at the same time, it can quickly conduct heat and improve heating efficiency. Hot pressing is an important process step in the manufacture of silicon nitride ceramic electric heating elements. By hot pressing, the silicon nitride ceramic powder is heated to a high temperature, so that the particles are combined to form a dense structure. This dense structure ensures the mechanical strength and thermal stability of the silicon nitride ceramic element. The manufacture of silicon nitride ceramic electric heating elements also requires consideration of the shape and size of the material. According to different application requirements, different forming methods can be used, such as pressing, injection molding and extrusion. After that, the density and stability of the silicon nitride ceramic electric heating element are further improved by high temperature heat treatment.
