The silicon nitride ceramic substrate boasts numerous advantages, such as high strength, high toughness, and exceptional thermal conductivity (130W/(m-k)).Furthermore, its thermal expan sion coefficient closely matches that of Si, SiC, and GaN semiconductors.Consequently, the silicon nitride ceramic substrate is an ideal choice for packaging high-power modules, making it widely regarded as the most suitable ceramic substrate option.

Our company utilizes the direct nitridation process to produce high-purity silicon powder. Through our unique patented technology, we control the silicon material, nitriding process, and refining process to prepare CF-HJ silicon nitride powder with high purity, a high a phase content, a narrow particle size distribution, and exceptional sintering activity. This type of silicon nitride powder has effectively terminated foreign monopolies and can serve as a fully viable substitute for imported silicon nitride powder of the same quality level.
