Title: Barium titanate-based semiconductor porcelain and its production
Inventor: GOTO TAIJI
IPC: H01C7/02
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To produce a semiconductor porcelain, capable of suppressing a rise in resistance value, improving the breakdown voltage and manifesting a positive resistance temperature coefficient by forming a composition containing a system, prepared by adding Bi2 O3 to barium titanate containing Y as a compositional system for providing a small average grain diameter within a specific range and mixed with a system obtained by adding Li2 CO3 to the barium titanate containing the Y as a compositional system for affording a large average grain diameter within a specified range. SOLUTION: This barium titanate-based semiconductor porcelain comprises large crystal grains having 20-30μm average grain diameter and small crystal grains having 1.0-5.0μm average diameter. When the average grain diameter of the large grain crystals is larger than 30μm, the mutual contact of the grains is increased to cause a deterioration in breakdown voltage and resistance value. When the average grain diameter of the small crystal grains is smaller than 1.0μm, a definite granular form is not manifested and the resistance value is raised to provide an insulator. At least either one of the two compositional systems is calcined and both are then mixed to carry out the glost firing. Thereby, a sintered compact having the large and the small grain diameters is obtained.
