    Spray dried Silicon Nitride Powder
    Silicon Nitride Powder is an important material of composite industry ceramics. Sinyo’s Si3N4 is made by Si powder and Nitrogen in reduction furnace which synthesis high purity alpha phase powder. The synthesis process has superiority in particle design with purity, morphology, crystal phase, grain size, its distribution and other important properties which can control the microstructure, and consequently it enhances thermomechanical properties required for final products such as strength, fracture toughness, hardness, thermal shock fracture resistance, thermal conductivity, etc. Our product is suitable for sintering precision Si3N4 ceramic.
    To make precision Silicon Nitride ceramic like bearing ball, good flow ability powder is easier to fill in mould and pore. The finished product density and strength will be uniform.
    ◆High alpha phase content.
    ◆High purity
    ◆Low Free Si.
    ◆Uniformity/Sharpness of particle size distribution.
    ◆Good flow ability
