Abstract
The invention provides a nano zirconia material, its preparation method and application. The dielectric constant of the nano-zirconia material is 18.01-19.97 at 20GHz, and the dielectric loss tangent is 0.0008-0.0027; the dielectric constant at 28GHz is 18.46-21.27, and the dielectric loss tangent is 0.0012-0.0035; The dielectric constant is 18.73-23.88, the dielectric loss tangent is 0.0041-0.0078; the dielectric constant at 65GHz is 19.75-25.35, the dielectric loss tangent is 0.0031-0.0073; the dielectric constant at 70GHz is 20.68-26.26, The dielectric loss tangent is 0.0043-0.0080. The nano-zirconia material has excellent dielectric properties and is suitable for applications such as 5G communication consumer electronics dielectric substrates, mobile phone backplanes, and fingerprint identification. It is a ceramic material that can be applied in the millimeter wave frequency band.
Description
Nano-zirconia material, its preparation method and application technical field The present invention relates to the field of inorganic nanomaterial preparation, specifically, relate to a kind of nanometer zirconia material, its preparation methods and applications. Background technique [0002] 5G has the characteristics of high speed, low latency (only 1ms latency), low energy consumption, and full network coverage. With communication equipment The operating frequency continues to increase, the signal delay will become more obvious, and the loss and heat generation of the system will also increase. The dielectric properties of the bond material are required to be higher. Nano-zirconia is a kind of ceramic material integrating superior electrical properties and mechanical properties, which is used in electronic ceramics. Porcelain, functional ceramics and structural ceramics have a wide range of applications. Zirconia has three crystal phases with different structu...
