High Purity Silicon Nitride Powder Silicon Nitride Powder
UBE SILICON NITRIDE is synthesized from Silicon tetra-Chloride and Ammonia.
The liquid interfacial reaction method, our proprietary process, has superiority in particle design with purity, morphology, crystal phase, grain size, its distribution and other important properties that can affect the favorable microstructural characteristics.
The asset of its top quality can realize not only properties required for the final application, such as excellent strength over a wide temperature range, good thermal shock characteristics, high toughness and hardness but also increase productivity and reduce defective products.
UBE SILICON NITRIDE has widened various final products for aircraft industries, automotive industries, metalwork, paper industries and also has been in general use as a kind of filler among several industries.
