PURPOSE:To find out substance having electric conductivity enough to meet the requirement even at a relatively low temperature by using an oxygen ion conductive solid electrolyte with a high conductivity which is a fluorine oxide having a specified composition. CONSTITUTION:For example, 1mol of neodymium oxide (Nd2O3) and 2mol of samarium fluoride (SmF3) or 1mol of samarium oxide (Sm2O3) and 2mol of neodymium fluoride (NdF3) are crushed and mixed and baked under the atmosphere of argon gas at 1,350 deg.C for about 3-4hr to make an oxygen ion conductive solid electrolyte of the formula. It is further made filmy by plasma spray, vacuum evaporation, sputtering or the like and thicker by hot pressing, rubber pressing, hot hydrostatic pressure sintering or the like. Thus, a substance can be determined having electric conductivity enough to meet the requirement even at a relatively low temperature. |
