A YAG transparent ceramic for white light LED lamps. Sintering raw materials comprise, by weight, 220-300 parts of Al2O3, 300-380 parts of Y2O3, 60-75 parts of SiO2, 15-20 parts of CeO2, 5-10 parts of Pr2O3, 2-5 parts of Eu2O3, 2-4 parts of Lu2O3, 1-2 parts of LiF, 3-5 parts of B2O3, 3-5 parts of SiC, and 0.5-1 part of CaO. The purity of all the raw materials is above 99.99 wt%. The transparent ceramic has a light transmittance in the visible light region of up to 65%-75%, and has a color temperature of 4000-5000 k. Compared with the prior art, the transparent ceramic is improved in aspects of shrinkage percentage, light transmittance, color rendering index, and color temperature, and has the characteristics of high thermal conductivity, good chemical stability, long service life, and high luminous efficiency.
