Low temperature co-fired ceramic material, low temperature co-fired ceramic body, and multilayer ceramic substrate

摘要

A low temperature co-fired ceramic material includes a SiO 2 -BaO-Al 2 O 3 -based primary component, and, as secondary components, 0.044 to 0.077 parts by weight of iron in terms of Fe 2 O 3 and 0.30 to 0.55 parts by weight of zirconium in terms of ZrO 2 relative to 100 parts by weight of the siO 2 -BaO-Al 2 O 3 -based primary component. The SiO2-BaO-Al 2 O 3 -based primary component preferably includes 47% to 60% by weight of SiO 2 , 20% to 42% by weight of BaO, and 5% to 30% by weight of Al 2 O 3 .
