Silicon Nitride Powder

Silicon nitride is a compound of silicon(59.4%) and nitrogen(38.2%). Si3N4 is the most thermodynamically stable of the silicon nitrides. It is a white, high melting solid that is relatively chemically inert. It has a melting point of approximately 2830°C and a density of 3.16 g/cm3. Silicon nitride’s high temperature properties are superior to most metals, combining high strength, creep resistance, and oxidation resistance.

Introduction to Silicon Nitride Powder

The material is currently used in market segments such as reciprocating engine components and turbochargers, bearings, metal cutting and forming tools, and hot metal processing. Silicon nitride powder has excellent strength and creep resistance at high temperatures and is very resistant to thermal shock, making it an important high temperature structural ceramic. Silicon nitride is also of interest as an electronic thin film material in optical coatings, insulating layers, or diffusion barriers.
