Features of the original silicon nitride heater
Silicon nitride heating element is a kind of important high-temperature structural ceramics. It has the characteristics of small thermal expansion coefficient, high hardness, high elastic modulus, thermal temperature performance, chemical stability, and good insulation. In addition, it is also resistant to oxidation and corrosion. The advantages make it have great application prospects. Pure silicon nitride does not absorb microwave energy at room temperature, and is almost microwave transparent, relying on its own dielectric loss to heat.
The silicon nitride heating element is small in size, light in weight and high in power density. Power >100W/cm2, much higher than 2-8 W/cm2 of ordinary metal heating body and 20-80W/cm2 of ordinary silicon nitride ceramic heating body.
Through the improvement of the development of molding and sintering technology, it is possible to prepare a silicon nitride ceramic heating element with a relatively complex shape, such as a cylindrical shape, that can achieve any temperature data distribution. Compared with the traditional sheet ceramic heating element, it has its own higher thermal efficiency and thermal shock resistance, and the product design life is greatly improved;
Research on the special ceramic heating body for silicon nitride, and prepare a new type of silicon nitride ceramic heating body through formula improvement, process selection, and sintering process improvement. The silicon nitride heating body mainly has the following characteristics:
1. The silicon nitride heating element has the advantages of small size, light weight, and high power density.
2. By improving the molding and sintering process, it is possible to prepare silicon nitride ceramic heaters with complex shapes, such as cylinders, that can achieve arbitrary temperature distribution. Compared with traditional chip ceramic heaters, it has higher thermal efficiency and thermal shock resistance, which greatly improves the service life of the product
3. Excellent thermal performance. The heating efficiency is above 98%, and it can reach a high temperature of 800-1000°C in a few seconds. It can directly heat water, gas, kerosene, metal and other media without noise and pollution;
4. The silicon nitride heating element has high reliability.
