Method for making a ceramic intergranular barrier-layer capacitor

摘要

A donor modified strontium titanate formulated to become conductive when sintered in air, is further modified with a minute quantity of manganese and sintered to maturity in a nitrogen atmosphere. A paste including silver particles, and oxides of bismuth and copper is applied to two major portions of the body. The coated body is heated at about 920 DEG C. to oxidize the grain boundaries and to form silver electrodes tightly adhered to the body.
