PURPOSE:To enable stable production of an ion selective ceramic electrode element having a high sintered density of the element, a high yield and a long life by calcining and pulverizing lanthanum fluoride then adding a binder to the powder and molding the mixture under pressurization. CONSTITUTION:After the lanthanum fluoride powder is calcined and pulverized, the org. binder is added to the powder and the mixture is molded. The binder is once decomposed and splashed within a 300-600 deg.C range in air and thereafter, the molding is sintered by heating in an inert gas. The electrode element which has good moldability and has no open pores is thereby manufactured and the ion selective ceramic electrode element having the high yield and long life is stably produced. |
