Low-temperature sintering porcelain material

摘要

PURPOSE:To perform sintering at a temperature not more than 1000 deg.C, to obtain permittivity of 17-80, and to decrease a ratio of temperature variation of the permittivity by using a specified composition of material. CONSTITUTION:A material that includes 44.0-99.5mol% of ZrO2,0-44.775mol% of TiO2, and 0.5-15mol% of CuO, for 100mol% in total, is used and is molded by dry press, and sintered at a temperature of 1000 deg.C, so as to form a porcelain. Mn can be added by 5.0 weight% or less calculated MnCo3 equivalent. By adding Mn, resistivity is increased, and insulating resistance can be improved.
