Low-temperature co-fired ceramic material and preparation method thereof
The invention provides a low-temperature co-fired ceramic material and a preparation method thereof. The low-temperature co-fired ceramic material comprises the following raw material components in percentage by mass: 27%-30% of Li2O, 17%-44% of SrO, 7%-29% of CaO and 22%-25% of SiO2. According to the low-temperature co-fired ceramic material, a phase with a low-melting-point Li4SrCaSi2O8 structure is generated, so that the sintering temperature can be reduced without additionally adding a glass phase. In addition, the dielectric constant of the low-temperature co-fired ceramic material can be 8.4-9.5 by regulating and controlling the content of strontium oxide and calcium oxide in the raw materials; the Q * f value ranges from 41300 GHz to 64000 GHz; the temperature coefficient of resonance frequency is-140 to-60 ppm/DEG C, and the ceramic is expected to be used for manufacturing microwave devices such as low-temperature co-fired ceramic substrates, microwave integrated circuit substrates, resonators, electronic product packages and the like.
本申请提供了一种低温共烧陶瓷材料及其制备方法，所述低温共烧陶瓷材料包括如下质量百分含量的原料组分：27％～30％Li2O，17％～44％SrO，7％～29％CaO，以及22％～25％SiO2。该低温共烧陶瓷材料由于生成了低熔点的Li4SrCaSi2O8结构的物相，所以无需额外添加玻璃相就有降低的烧结温度。另外，通过调控原料中氧化锶和氧化钙的含量，可使所述低温共烧陶瓷材料的介电常数为8.4～9.5；Q×f值为41300～64000GHz；谐振频率温度系数为‑140～‑60ppm/℃，有望作为低温共烧陶瓷基板、微波集成电路基片、谐振器与电子产品封装等微波器件的制造。
