摘要
The porous silicon nitride was prepared by reaction-bonded raw silicon powder and silicon nitride whiskers, adding 30wt% pore-forming agent and polyvinyl alcohol. The impacts of silicon nitride whiskers on the properties of reaction-bonded porous silicon nitride ceramics were particular studied. The results showed that the dielectric constant and dielectric loss were all raised with the increase of addition of silicon nitride whiskers. The silicon nitride whiskers deteriorate the dielectric properties of porous silicon nitride ceramics.
