Title:
PRODUCTION OF DIELECTRIC AND COAXIAL DIELECTRIC RESONATOR PRODUCED BY THIS METHOD
Document Type and Number:
Japanese Patent JP3453853
Kind Code:
B2
Abstract:
PURPOSE: To form a conductor layer by calcining a hollow dielectric in a reducing atmosphere.
CONSTITUTION: An organic adhesive is added to the powdery mixture obtained by wet mixture and dehydration drying of powder of a (Zr.Sn)TiO4 and that of a nickel oxide in 9:1 by weight, and they are mixed and granulated. Obtained granules are loaded into a coaxial hollow square pillar and are pressed by 200kg/cm2 to form a molding 1. The molding 1 has one end face, which corresponds to the open end, turned down and is closely put on the upper face 2, to which a zirconia oxide is melt-sprayed, and is set in the atmosphere, and thereafter, the organic adhesive is removed in two hours at 400°C. Then, it is calcined in the same atmosphere in four hours at 1300°C. Next, H2+N2 (20% H2 concentration) is charged into the atmosphere to form the reducing atmosphere, and it is subjected to heat treatment in two hours at 1100°C, thus completing a dielectric 3 where an inner conductor layer 4, an outer conductor layer 5, a short-circuit conductor layer 6, and an inner peripheral hole 7 are formed in prescribed parts.
