Production of Permeable Fibrous Materials Composed of Silicon Nitride

  • Published:
Refractories and Industrial Ceramics Aims and scope

A technology which involves spraying a silicon-based thixotropic thermoplastic slip with a paraffin-based binder onto a rotating substrate-target is used to obtain a material that based on reaction-sintered silicon nitride and has a porous, permeable, fibrous framework-like structure. The fibers are distributed evenly over the surface of the substrate and are deposited on it in varying directions at low rates allow heat to be removed from the product. This results in the formation of fibrous framework-like structures that retain their original porosity as they subsequently undergo heating and a certain amount of contraction in the height direction. They can be used as porous partitions for the delivery and combustion of natural fuels in power plants and as filters for removing slag inclusions and oxide films from melts.
