The working principle of electric sintering furnace is mainly based on electric heating technology. It uses heating elements such as resistance wires, silicon carbide rods, or electromagnetic induction to convert electrical energy into thermal energy and heat the materials inside the furnace. As the temperature increases, the atoms or molecules inside the material begin to move more vigorously, gradually reaching the temperature required for sintering, and then undergoing physical or chemical changes such as densification and grain growth, ultimately forming the desired product.

Sintering furnace is an important material processing equipment, mainly used to heat powdered or other forms of raw materials to a molten or semi molten state through high temperature, and then cool and solidify them to obtain solid blocks with certain strength and density. This device has wide applications in various fields such as ceramics, metals, and glass, and is one of the important tools for preparing these materials.
