Porous Silicon Nitride Prepared by Cold Isostatic Pressure

摘要

Porous silicon nitride with pore forming agent of starch were prepared by cold isostatic pressing, forming problem of complex shapes were solved by methods of carbonization of starch and decreasing forming pressure. Products of porous silicon nitride had the performance parameter with density 1.5g/cm~3, porosity over 55%, bending strength over 100 MPa.
