The present invention discloses a zirconia ceramic substrate for an LED, characterized in that: all raw materials used in an LTCC preparation process are optimized; zirconia, boron nitride, aluminium oxide, and hydroxyapatite are used as main raw materials; meanwhile addictives such as a glass sintering aid, copper nanoparticles, a solvent, a plasticizer, a dispersant, and a binder are added; and physicochemical properties of the ceramic substrate are further optimized. According to the application, the thermal conductivity of the ceramic substrate is greater than 500W/(m.k), the bending strength is greater than 350 Mpa, the dielectric constant is less than 1.5. Meanwhile, by a conventional LTCC preparation method, main raw materials and addictives can be used to prepare a ceramic substrate with high conductivity, and the preparation method is simple, and is easy to be industrialized.
