Titanium nitride ceramic substrate for LED
The invention discloses a titanium nitride ceramic substrate for an LED. According to the titanium nitride ceramic substrate, various raw materials in the LTCC preparation process are optimized, titanium nitride is used as the main raw material, aluminum nitride, aluminum oxide, yttrium oxide and natural zeolite are added in a supplementary mode and used as the main raw materials, addition agents such as glass sintering aids, copper nanometer particles, solvent, plasticizer, dispersing agents, bonding agents and toughened fibers are added, and then the physical and chemical performance of the ceramic substrate is optimized. The thermal conductivity of the ceramic substrate is larger than 800W/(m.k), bending strength is larger than 400 MPa, and the dielectric constant is smaller than 2; meanwhile, by means of a conventional LTCC preparing method, the main raw materials and the addition agents can be prepared into the ceramic substrate with the high conductivity, and the preparation process is simple and beneficial for industrialization.
