To provide an electrode material for an electric light and its manufacturing method.
An electronic radiation composition includes a barium tantalate composition of a formula (Ba1-x, Cax, Srp, Dq)6(Ta1-y, Wy, Et, Fu, Gv, Caw) 2O (11±sigma). In the formula, sigma is the amount of approximately zero to -3, D is an alkaline earth metal ion or an alkaline earth metal ion, E, F and G are alkaline earth metal ions, alkaline earth metal ions and/or transitional metal ions, x is the amount of maximum about 0.7, y is the amount maximum about 1, p and q are amounts of maximum about 0.3, t is the amount from 0.05 to 0.10, u is the amount of maximum about 0.5, v is the amount of maximum about 0.5, and w is the amount of maximum about 0.25. The manufacturing method of the electronic radiation composition includes a stage in which the barium tantalate composition and a binding agent are blended, and a stage in which the barium tantalate composition having the binding agent is sintered at temperatures from about 1,000°C to about 1,700°C.
