Abstract As a critical concept in physical chemistry, superwettability is widely concerned both fundamental science and practical engineering past few decades. Despite this, investigation on high temperature still void, which significant scientific industrial fields. Herein, ceramic with specific non‐wetting property, Si 2 N O proposed. Compared other materials, elucidated better property against various non‐ferrous metals. Combining micro‐nanostructures, the metallophobicity further improved (contact angle >150° contact hysteresis ≈0°). The extraordinary metal repellency defined as “super‐metallophobicity”, proved to be induced by distinctive thermodynamic dynamic wetting behavior rough surface. research of super‐metallophobicity not only sheds light at temperature, but also offers worthy insights for future potential material design wide range applications, such metallurgy, 3D printing semiconductor industry.
