aluminum nitride ceramic in electronic cigarette

The application of aluminum nitride in e-cigarettes is mainly reflected in the preparation of its high heat generation efficiency e-cigarette atomizing core. 

Aluminum nitride (AlN), as a material with excellent thermal conductivity, has applications not only limited to heat dissipation substrates and electronic device packages, but also includes heat exchangers and functional materials and other fields. In the field of electronic cigarettes, the application of aluminum nitride is mainly embodied in the preparation of its high thermal efficiency electronic cigarette atomized core. The heat generating structure of such an atomized core employs a NiCuSiAl heat generating coating, and by controlling the components in the layer at an appropriate ratio, a coating with a low resistivity and a high electro-thermal conversion coefficient is formed. This coating enables the prepared atomizer core to be rapidly heated from room temperature to 600°C at a small rated power of 12W or less to achieve a large and full smoke volume. In addition, by providing a transition layer and a protective layer, this type of atomizer core not only has a good heating effect, but also better prevents oxidation and easy peeling of the heating coating, which extends the service life of the atomizer core1.

This application demonstrates the potential of aluminum nitride in improving the thermal efficiency of e-cigarette atomizer cartridges, which enhances the user experience by optimizing the thermal conductivity and thermal stability of the material, and also provides a new material solution for the development of e-cigarette technology.
