| Abstract: | The new-type composite with low thermal expansion coefficient and matching with silcon chips was developed. Effects of added mass fraction of ZnO, sintering temperature and microstructure on its properties were also investigated. Results show, its main properties are as follows: when w(ZnO) is 8%, the composites are sintered at 1 000 ℃ for 0.5 h, the εr, tanδ, bending strength, and αl of the composites are 6.48, 4.00×10–3, 76.29 MPa and 3.44×10–6℃–1 (25~500 ℃ ), respectively. |
