· NaSi2N3

Sodium silicate nitride (NaSi₂N₃) is an advanced ceramic compound combining silicon nitride with sodium incorporation, belonging to the family of non-oxide structural ceramics. This material is primarily of research and developmental interest, explored for high-temperature applications where thermal stability, chemical resistance, and mechanical integrity are critical; its potential applications span advanced engine components, wear-resistant coatings, and high-temperature structural applications in aerospace and industrial gas turbine environments where traditional oxide ceramics may degrade.
