Preparation method of low-temperature sintered electronic ceramic material

Abstract

The invention discloses a preparation method of a low-temperature sintered electronic ceramic material. The preparation method comprises the following steps: mixing a plurality of preparation raw materials according to the proportions; grinding the raw materials and adding the ground raw materials into a solvent; preparing suspension by adding a suspending agent, and enabling suspension slurry toflow to a stably-rotating annular steel strip through a casting nozzle by means of gravity; carrying out circular drying for multiple times to obtain a raw material thin film; adding a binder and a plasticizer into the raw material thin film; carrying out first-time mixing and grinding by a ball mill to obtain mixed material powder; putting the mixed material powder into a drying oven. According to the preparation method disclosed by the invention, the density of a blank body is more uniform; the quality of the obtained electronic ceramic material is high, and the electronic ceramic material can be prepared by low-temperature sintering forming; when the obtained electronic ceramic material is cofired, metals with better properties such as silver with better conductive property can be used;meanwhile, a formula is simple and low in price, so that the preparation cost of the low-temperature sintered electronic ceramic material is reduced.

Description

technical field

[0001] The invention relates to the technical field of electronic ceramic materials, in particular to a preparation method of low-temperature sintered electronic ceramic materials. Background technique

[0002] Electronic ceramics refer to ceramics that can use electricity and magnetic properties in the electronics industry. Electronic ceramics are ceramics with new functions that are finally obtained through precise control of the surface, grain boundaries, and dimensional structures. They are used in energy, household appliances, automobiles, etc. It can be widely used in the production of electronic functional components, most of which are sintered materials mainly composed of oxides. The manufacturing process of electronic ceramics is roughly the same as that of traditional ceramics. In terms of chemical composition, microstructure and electromechanical properties, All of them are essentially different from general power ceramics. These differences are fo...
