Preparation process of ceramic base plate for high-power LED (light emitting diode) heat radiation
The invention belongs to the technical field of a ceramic base plate, and particularly relates to a preparation process of a ceramic base plate for high-power LED (light emitting diode) heat radiation. The preparation process comprises the following steps of 1, preparing composite sintering auxiliary agents; 2, preparing ceramic slurry; 3, forming ceramics. The preparation process has the following beneficial effects that 1, the heat conduction coefficient of the ceramic base plate is great, the heat-resistant performance is excellent; the bending-resistant intensity is high, and phenomena such as bending and tilting are avoided; 2, a proper sintering method is used, and the proper sintering auxiliary agents are selected, so that the compactness of alumina ceramic sintering bodies is realized, and the heat conductivity of the alumina ceramics is greatly improved; 3, low-melting point phases can be formed by the sintering auxiliary agents, the liquid-phase sintering can be realized, the sintering temperature is lowered, and the blank compactness is promoted; 4, melamine in a recipe can produce aluminum nitride and carbonitride at high temperature, and the hardness and the lustrousness of the surface of the ceramic base plate are improved.
