Silicon Nitride Granulation Powder

Name

Silicon Nitride Granulation Powder
Features

Silicon nitride granulation powder is characterized by high dispersibility, homogeneity, purity, and reactivity. We utilize advanced sintering techniques to significantly enhance the density and mechanical properties of silicon nitride ceramics, leading to their widespread applications in high-end industrial sectors such as electronics, energy, petrochemical refining, and optical components.
Explanation

The silicon nitride granulation powder produced by JFM is made from high-purity raw materials, ensuring good flowability and fillability, making it suitable for dry pressing processes. Its uniform particle size and sphericity enhance the post-sintering density and uniformity, resulting in high strength and good fracture toughness. Utilizing advanced dry pressing and cold isostatic pressing techniques
