Low-temperature co-fired ceramic material with low dielectric loss and wide sintering process window and preparation method thereof
The invention discloses a low-temperature co-fired ceramic material with low dielectric loss and a wide sintering process window and a preparation method of the low-temperature co-fired ceramic material. The low-temperature co-fired ceramic material is prepared from the following components in percentage by mass: 50wt%-70wt% of calcium borosilicate lead glass and 30wt%-50wt% of aluminum oxide ceramic. The preparation method comprises the following steps: preparing calcium borosilicate lead glass powder, preparing composite powder, and molding and sintering the composite powder at low temperature. The low-temperature co-fired ceramic material disclosed by the invention has very low dielectric loss, and the dielectric loss of the material measured at 20MHz is between 3 * 10 <-5 > and 8 * 10 <-4 >; meanwhile, a very wide sintering process window is provided, sintering can be carried out between 700 DEG C and 900 DEG C, the sintering densification degree is high, and the co-sintering matching performance with silver paste is good.
本发明公开了一种低介电损耗、宽烧结工艺窗口的低温共烧陶瓷材料及其制备方法。该低温共烧陶瓷材料是由钙硼硅铅玻璃和氧化铝陶瓷组成，按质量分数计，钙硼硅铅玻璃为50wt％～70wt％，氧化铝陶瓷为30wt％～50wt％。制备方法包括钙硼硅铅玻璃粉体的制备，复合粉体的制备，以及复合粉体的成型和低温烧结。本发明的低温共烧陶瓷材料具有非常低的介电损耗，在20MHz下测得材料的介电损耗在3×10‑5～8×10‑4之间；同时具有非常宽的烧结工艺窗口，在700℃到900℃之间均可以烧结，且烧结致密化程度高，与银浆共烧匹配性好。
