ALPHA-SiAlON POROUS CERAMIC, AND PREPARATION METHOD AND USE THEREOF

Abstract

Provided are an α-SiAlON porous ceramic, and a preparation method and use thereof. The α-SiAlON porous ceramic has a dielectric constant of 1.19 to 3.21 at 12 GHz, a dielectric loss of 0.33×10−3 to 11.17×10−3, a thermal conductivity of 0.31 W/(m·K) to 0.81 W/(m·K) at room temperature, a thermal conductivity of 0.14 W/(m·K) to 0.59 W/(m·K) at a temperature of 1,500° C., and a bending strength of 72.4 MPa to 184.4 MPa.
