LTCC ceramic material as well as preparation method and application thereof
The invention discloses an LTCC ceramic material as well as a preparation method and application thereof. The LTCC ceramic material disclosed by the invention comprises the following components in percentage by mass: 30 to 40 percent of KBS glass powder and 60 to 70 percent of spherical SiO2. By adding the spherical SiO2, the dielectric constant of the LTCC is effectively reduced, so that the dielectric constant of the material is as low as 3.7, and the dielectric loss is as low as 0.2%; the sphericity degree of the spherical SiO2 is greater than or equal to 98%, and the spherical SiO2 is graded by SiO2 with three particle sizes, so that the sintering compactness of the material is improved, and the porosity of a sintered ceramic body is as low as 0.09%. The LTCC ceramic material disclosed by the invention has the advantages of ultralow dielectric constant, low loss and good compactness, and is suitable for the fields of high-frequency communication and radio frequency.
本发明公开了一种LTCC陶瓷材料及其制备方法与应用。本发明的LTCC陶瓷材料包括如下质量分数计的组分：30‑40％的KBS玻璃粉、60‑70％的球形SiO2。通过添加球形SiO2，有效降低LTCC陶瓷介电常数，使得材料介电常数低至3.7，介电损耗低至0.2％；球形SiO2的球形度≥98％，且以三种粒径SiO2级配，提高了材料的烧结致密性，使得烧结陶瓷体气孔率低至0.09％。本发明的LTCC陶瓷材料具有超低介电常数，损耗较低，且致密性良好，适用于高频通讯及射频领域。
