PROCESS OF MANUFACTURE OF SEMICONDUCTOR CERAMIC MATERIAL BASED ON BARIUM TITANATE DOPED WITH NIOBIUM Russian patent published in 1996 - IPC

FIELD: electronics. SUBSTANCE: invention refers to manufacture of temperature-sensitive resistors with positive resistance factor-positrons. First wet mixing of components of raw materials is conducted in quantities corresponding to formula composition of solid solution, then preliminary firing and milling of sinter by wet method are performed followed by injection of solution of pentamethilate of niobium in methanol with intention to obtain solid solution of type BaTi_1-xNb_xO₃ where x=0.1-0.2 atomic per cent. During mixing ammonia solution is added. EFFECT: improved quality of material. 1 tbl
