High-Q-value low-dielectric-constant LTCC powder, LTCC material, preparation method of LTCC material, raw ceramic tape, preparation method of raw ceramic tape and application of raw ceramic tape
The invention discloses an LTCC material with a high Q value and a low dielectric constant, a green ceramic tape and a preparation method thereof, LTCC powder is formed by mixing raw materials including Mg2SiO4 and CuF2, the weight of the CuF2 is 1-6% of the weight of the Mg2SiO4, the CuF2 is adopted as an additive, the sintering temperature can be reduced, the CuF2 can react with Mg2SiO4 ceramic to cause lattice distortion, a crystal structure is finely adjusted, and the dielectric constant of the Mg2SiO4 ceramic is improved. The Q * f value and the temperature stability are enhanced, the problem that an existing LTCC material is high in dielectric loss under the GHZ high frequency is solved, and the LTCC material can be used in the field of high-frequency integration.
本发明公开了一种高Q值低介电常数LTCC材料、生瓷带及其制备方法，所述LTCC粉由包括Mg2SiO4和CuF2的原料混合而成，且所述CuF2的重量为所述Mg2SiO4重量的1‑6％，其采用CuF2作为添加剂，不仅能够降低烧结温度，还会与Mg2SiO4陶瓷发生反应导致晶格畸变，并对晶体结构进行微调，增强Q×f值和温度稳定性，解决了现有LTCC材料在GHZ高频下介电损耗高的问题，可用于高频集成领域中。
