Embodiment Construction
[0037] As a preferred embodiment, the technical process see figure 1 ,right figure 1 A method for manufacturing a nanostructure composite LED ceramic substrate according to the steps shown, is characterized in that it comprises the following steps:
[0038] a. Mixing powder, according to the weight percentage of the powder, 80% of alumina with a purity of >95%, 15% of zinc oxide and magnesium oxide, 5% of rare earth elements and nano-inorganic polymers, among which nano-inorganic polymers are one-dimensional Any value <100nm, the particle size of the rest of the powder is 1~2μm, the ambient temperature is maintained between 15°C~25°C, the temperature is 65%, and the circulating wind speed is less than 0.5m / s;
[0039] b. Mixing, mix the prepared powder and pure water in a ratio of 1:2 to form a slurry, and add an appropriate amount of chemical abrasive to the code name CM5, the resistance value of pure water is >5MΩ, and the pure water is allowed to stand It should not excee...
