Combustion synthesis of porous ceramic β- Si3N4 -based composites with the use of ferroalloys

A method for manufacturing silicon nitride-based composites with a desired porosity using a self-propagating high-temperature synthesis has been developed. The effects of the composition of starting specimens, pressure and diameter on the combustion parameters of pre-structured specimens based on ferro-silicoaluminum with addition of aqueous-alkali solution were studied. The phase composition of composites was determined. The obtained composites showed porosities of 25.11%–55.08% with a predominance of open pores of average size in the range of 21–305 μm.

Microstructure and permeability of porous Si3N4 supports prepared via SHS

Porous Si₃N₄ ceramics with tailored pore structures were fabricated via self-propagating high temperature synthesis (SHS) using Polymethylmethacrylate (PMMA) as pore forming agent. The pore structures, mechanical properties and permeation performance of porous Si₃N₄ ceramics were investigated by altering the particle sizes and amount of PMMA. With the increasing content of PMMA, the flexural strength of samples decreased from 102.5 MPa to 9.4 MPa. The tortuosity which showed irregular variation affected gas permeability directly. The samples with 20 wt% content of PMMA exhibited the maximum Darcian and non-Darcian constants with the smallest tortuosity. Moreover, the comparison of permeability coefficients with other ceramics via different pore forming methods in literature was presented. The specimens exhibited great permeability due to the large pore sizes created by the elongated and coarsened β-Si₃N₄ grains during the SHS process, providing a low-cost and environmentally friendly method for preparing high permeability porous Si₃N₄ supports.
