CERAMIC COMPOSITION BEING FIRED AT LOW TEMPERATURE AND HAVING HIGH STRENGTH AND METHOD FOR PREPARING THE SAME, AND LAMINATED ELECTRONIC PARTS USING THE SAME

摘要

A high-strength, low-temperature-sintered ceramic composition having a structure comprising a SrAl2Si2O8 crystal and an Al2O3 crystal, the SrAl2Si2O8 crystal being composed of hexagonal SrAl2Si2O8 alone or hexagonal SrAl2Si2O8 and monoclinic SrAl2Si2O8, and a peak intensity ratio represented by I101 / (I101 + I002) x 100 being 5% or more in an X-ray diffraction measurement by a Cu-K alpha line, wherein I101 represents a peak intensity of a (101) plane of the hexagonal SrAl2Si2O8, and I002 represents a peak intensity of a (002) plane of the monoclinic SrAl2Si2O8.
