The invention discloses a ceramic for ceramic LED lamps. The ceramic is formed through grinding components and firing the ground components, and the components comprise 50-60 parts of aerated aluminum powder, 60-70 parts of aluminum nitride, 30-45 parts of mica powder, 40-50 parts of calcite powder, 6-8 parts of lead trioxide, 8-10 parts of samarium oxide, 8-10 parts of boron nitride, 12-15 parts of born carbide, 20-25 parts of silicon micro-powder, 25-35 parts of molybdenite powder, 5-8 parts of nanometer magnesium oxide, 8-10 parts of titanium dioxide, 8-10 pars of zirconium dioxide and 12-15 parts of silicon nitride. The ceramic for ceramic LED lamps can effectively solve the problems of firing fracture, deformation and high defective index of present ceramics, can shorten the pre-burning and sintering time, reduces the sintering temperature , greatly saves energy, reduces energy consumption, is environmentally-friendly and reduces the production cost, grains of sintered products are fine and uniform and have high density, the fracture toughness of the ceramic material is effectively improved, sintering deformation is well controlled, the sintered ceramic material is integrally balanced, wastes are greatly reduced, and the quality of the products is improved.
