Abstract

A low-temperature co-fired ceramic material comprises the following components in percentage by weight: 35-50% of CaO, 5-15% of B2O3, 40-55% of SiO2, 1-5% of nanometer Al2O3, 1-5% of MgO and 1-5% of nanometer ZrO2. A preparation method comprises the following steps: ball milling and mixing according to the formula, sintering at a high temperature, quenching in deionized water, grinding, performing wet ball-milling, drying and grinding; and finally, granulating to prepare a green body, discharging glue, and sintering, to obtain a low-temperature co-fired ceramic material. According to the low-temperature co-fired ceramic material and the preparation method thereof provided in the present disclosure, the prepared low-temperature co-fired ceramic material has the advantages of low dielectric constant, low loss, good overall performance and the like.
