摘要:
The present disclosure discloses a ceramic (10), an atomization core (20), and an atomizer (100). The ceramic (10) includes a ceramic base (11) and a modification layer (12). The modification layer (12) is arranged on a surface of the ceramic base (11), and the modification layer (12) includes a bismuth-based oxide and other compositions. By optimizing the formulation of the modification layer (12) by adding the bismuth-based oxide in the modification layer (12), lead-containing oxides in the related art are replaced with the bismuth-based oxide. Therefore, the melting temperature of the modification layer (12) is lowered, the firing range of the modification layer is expanded, the thermal expansion coefficient of the modification layer (12) is lowered, and the thermal shock resistance and the tensile deformation resistance of the modification layer (12) are improved, thereby improving performance of the atomization core (20), and further improving performance of the atomizer (100).
