Abstract

The invention discloses a ceramic material with a low dielectric constant. The ceramic material is prepared from the following materials in parts by weight: kaolin, anorthite, akermanite, sodium carboxymethyl cellulose, calcium titanate, polyvinyl alcohol, nanometer bismuth trioxide, boron oxide, zinc nitrate, magnesium cordierite, fluorite, tremolite, clinochlore, pyrophyllite and yttrium aluminum garnet. Zinc ions in zinc nitrate can substitute magnesium in akermanite; the akermanite having magnesium substituted with the zinc ions can be matched with boron oxide to reduce a sintering temperature, and can be matched with calcium titanate to adjust the temperature stability, thereby avoiding heating fragmentation and reducing the dielectric constant; yttrium ions in the yttrium aluminum garnet can improve particle size distribution and reduce porosity; a special octahedral six-membered rings of magnesium cordierite crystals enable the structure and performance to have adjustability; and the yttrium aluminum garnet can be matched with the magnesium cordierite to further reduce the dielectric constant and increase the stability.

Description
