Silicon Nitride (Si₃N₄) vs Aluminium Nitride (AlN) Ceramic Blocks: Performance, Specification and Application Analysis

Silicon Nitride (Si₃N₄) and Aluminium Nitride (AlN) ceramic blocks are both advanced structural ceramics that excel in extreme environments such as high temperatures, corrosion, and high loads due to their excellent physical and chemical properties. Silicon nitride is known for its high strength, high hardness and wear-resistant properties, while aluminum nitride stands out for its ultra-high thermal conductivity and insulating properties, both of which are used in complementary applications in aerospace, electronics, energy and other fields.
