TiAlN ceramic substrate for LED (light emitting diode)
The invention discloses a TiAlN ceramic substrate for an LED (light emitting diode), various raw materials in an LTCC (low temperature co-fired ceramic) preparation process are optimized, TiAlN is used as the main raw material, meanwhile, additives such as AlN, Al2O3 micropowder, MCM-41 molecular sieve, SiC, glass sintering aid, ferro-nano particles, rare earth oxide, solvent, plasticizer, dispersant and binder are added, the physical and chemical properties of the ceramic substrate is further optimized, heat conductivity of the ceramic substrate is larger than 1000W/(m.k), bending resistance is larger than 500Mpa, and a dielectric constant is smaller than 3. Meanwhile, through a conventional LTCC preparation method, the main raw material and the additives can be prepared into the ceramic substrate with high conductance, and the preparation process is simple and favorable for industrialization.
