Silicon Nitride Ceramics: The Future Star Of High-performance Materials

Introduction

With the rapid development of industry and technology, the demand for high-performance materials is growing. Silicon nitride ceramics (Si₃N₄) have become a “star material” in the fields of aerospace, electronics, and medical due to their unique physical and chemical properties. This article will deeply analyze the characteristics, application scenarios, and market potential of silicon nitride ceramics to help you understand the core value of this material. Ingredients: The Al2O3 content is usually 75%~99.9%. The higher the purity, the better the performance (such as 99.6% high-purity alumina ceramics).Classification: According to the purity, it is divided into ordinary type (75%~95%) and high-purity type (≥99%).
