Low-dielectric LTCC green tape as well as preparation method and use thereof

The invention discloses a low-dielectric LTCC green tape as well as a preparation method and use thereof. The low-dielectric LTCC green tape is composed of a powder, a solvent, a dispersing agent, a binder and a plasticizer, wherein the powder is in a mass fraction of 40-60%, and prepared from 10-40wt% of a glass material, 1-10wt% of a low melting point oxide sintering aid and the balance of a ceramic material; the chemical composition of the ceramic material is Zn2-xSiO4-x, where x=0.05-0.3. In the present invention, the problem of low-temperature sintering ofZn2-xSiO4-x ceramic is solved byadding the crystallizable glass material and the sintering aid together, and the mechanical properties and the high-frequency electrical characteristics of the system can be improved. 本发明公开了一种低介LTCC生瓷带及其制备方法和用途，其由粉体、溶剂、分散剂、粘结剂和增塑剂组成，所述粉体的质量分数为40-60%，其是由10~40wt%玻璃材料、1~10wt%低熔点氧化物烧结助剂和余量的陶瓷材料制备而成的，所述陶瓷材料的化学组成为ZnSiO，其中x=0.05~0.3。在本发明中，通过应用可析晶玻璃材料以及烧结助剂的复合添加，解决了ZnSiO陶瓷的低温烧结问题，同时又能够提升体系的机械特性及高频电学特性。
