Abstract

The invention discloses a method for preparing a microcrystalline ceramic backplane without shielding based on 5G communication signals, respectively weighing high-purity Y 2 o 3 Powder, high purity Gd 2 o 3 Powder and high purity ZrO 2 The powder is used as the raw material powder, adding dispersant, plasticizer, and binder for ball milling; after filtering, it is directly tape-cast, and the obtained green body is custom-cut and stacked, and the obtained green body is subjected to temperature control. Static pressure, shaping, and then degreasing; the degreased green body is vacuum sintered, and after being naturally cooled to room temperature, it is added to liquid nitrogen for storage for a period of time, and the ceramics are taken out of the liquid nitrogen and directly placed in a vacuum sintering furnace for sintering again , and annealed after naturally cooling to room temperature to obtain a microcrystalline ceramic backplane. The microcrystalline ceramic back plate prepared by the invention has superior performance, has no shielding for 5G communication signals, has good jade texture and luster after polishing, and has low preparation cost and simple preparation process.

Description

technical field [0001] The invention relates to the technical field of ceramic backplane preparation, in particular to a method for preparing a microcrystalline ceramic backplane based on 5G communication signals without shielding. Background technique [0002] With the great breakthroughs in science and technology, the Internet of Things industry has developed rapidly; the mobile communication network has also developed from 2G, 3G to 4G, changing people's lives step by step. Now that 5G signal base stations are becoming popular, it marks the arrival of the era of the Internet of Everything, which means that smart products based on 5G communication networks have become the mainstream of the market. At present, major electronic product manufacturers have launched their own electronic products based on 5G communication networks. [0003] However, the 5G communication network based on the millimeter wave (MMW) data transmission method has key technical problems such as unstab...
