Millimeter wave ultralow-dielectric low-loss LTCC material and preparation method thereof, and green tape and preparation method thereof
The invention discloses a millimeter-wave ultralow-dielectric low-loss LTCC material and a preparation method thereof, and a green tape and a preparation method thereof. The LTCC material and the green tape are prepared from the following raw materials: magnesium lithium borosilicate glass, aluminum oxide and silicon oxide; the magnesium-lithium borosilicate glass comprises the following raw materials: magnesium oxide, lithium carbonate, boric oxide and silicon oxide, and the mass ratio of the magnesium oxide to the lithium carbonate to the boric oxide to the silicon oxide is (10-20): (10-20): (20-30): (30-60). The relative dielectric constant epsilon r of the LTCC material and the raw ceramic tape prepared by the method is 3.2-4.8, the dielectric loss is less than or equal to 0.001, and the bending strength is 180-200MPa, so that the transmission loss of electromagnetic signals under high frequency can be reduced, and the signal transmission speed can be increased. Meanwhile, low-temperature sintering can be conducted at the temperature of 820-900 DEG C, cofiring matching with Ag is achieved, and good chemical compatibility is achieved.
本发明公开了一种毫米波超低介低损耗LTCC材料及其制备方法和生瓷带及其制备方法，LTCC材料和生瓷带的原料包括镁锂硼硅玻璃、氧化铝和氧化硅；所述镁锂硼硅玻璃的原料包括氧化镁、碳酸锂、氧化硼和氧化硅，且所述氧化镁、碳酸锂、氧化硼和氧化硅的质量比为10～20：10～20：20～30：30～60。本发明制备的LTCC材料和生瓷带的相对介电常数εr在3.2～4.8之间，介电损耗小于等于0.001，抗弯强度为180‑200MPa，这将有助于降低在高频下电磁信号的传输损耗和增大信号传输速度。同时，本发明可在820～900℃下进行低温烧结，与Ag共烧匹配，有好的化学兼容性。
