摘要:
A ceramic slurry or slip includes ceramic powder, an organic plasticizer and a resin binder combined in an aromatic hydrocarbon solvent and has a viscosity that is independent of shear rate. Monolithic ceramic capacitors having fewer pin holes are made by forming a falling sheet of this Newtonian slip, and repeatedly interrupting the falling curtain by passing a carrier through it to form layers of green ceramic. An electroding film is deposited on each green ceramic layer to form buried electrodes. The Newtonian slip is advantageously self leveling and contains relatively few pin holes that degrade capacitor performance.

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.degree. C. to oxidize the grain boundaries and to form silver electrodes tightly adhered to the body.
