Abstract

The invention discloses low-dielectric rare earth doped aluminoborosilicate glass powder and a preparation method thereof, and relates to the technical field of glass powder processing. The glass powder comprises the following components in percentage by mass: 58% of SiO2; al2O3: 10%; 20% of B2O3; 2% of CaO; 8% of MgO; and 2% of rare earth oxide. Rare earth elements are introduced into a glass phase as a network modifier, so that the bonding condition of a glass structure is changed, the structure and performance of a glass grid are influenced, and the dielectric property, chemical stability and the like of the glass grid are improved. The minimum dielectric constant of the prepared glass powder can reach 2.31, and the minimum dielectric loss tan theta is 0.0021.
