SOLID ELECTROLYTE AND THE METHOD OF ITS PRODUCTION Russian patent published in 2006 - IPC C04B35/48 C04B35/626 

FIELD: electrical industry; metallurgy; methods of production of the solid electrolyte.

SUBSTANCE: the invention is pertaining to production of the refractory products, in particular, to the method of production of the solid electrolytes from the powders of the refractory compounds and may be used in electrical industry and metallurgical branches of industry. The technical result of the invention is production of the solid electrolytes having the improved technological and operational properties. The method provides for production of the solid electrolyte from the nano-dispersive powders of the preset composition produced by the plasma-chemical method. The produced powders are preliminary subjected to the preliminary sequential thermal treatment at the temperature of 800-1400°C within 0.5-1 h. Then conduct the mechanical activation in the ball grinder with addition of the surface-active substance for 25-100 hours, mix it with the organic binder and fritting in the furnace within 10 hours at the temperature of 1200±20°C, and for 12 hours at increasing the temperature from 1200 up to 1600°C. Cool the mass for 0.5 hour from 1600 down to 1200°C, keep it for 10 hours. At the temperature of 1200°C with the subsequent chilling down to the room temperature together with the furnace. In the capacity of the surface-active substance use oleinic acid in amount of 1-2 mass %, and as the organic binder they use paraffin in amount of 16-20 mass %.

EFFECT: the invention ensures production of the solid electrolytes having the improved technological and operational properties.
