CERAMICS RAW MATERIAL COMPOSITION, INCLUDING THE HIGH FLEXURAL STRENGTH, THE HIGH REFLECTIVITY, AND THE LOW GLASS PHASE CRYSTALLINITY

摘要

PURPOSE: A ceramics raw material composition is provided to combine silicon oxide-aluminum oxide-boron oxide-calcium oxide-based glass composition, alumina, filler, high refractive index filler in order to be used for low temperature co-fired ceramics substrate.;CONSTITUTION: Ceramics raw material composition includes 20-50 weight% of borosilicate-based glass powder, 25-55 weight% of alumina filler powder, and 10-45 weight% of high refractive index filler powder. The borosilicate-based glass powder includes 30-70 weight% of SiO_2, 5-28 weight% of B_2O_3, 5-30 weight% of Al_2O_3, 3-35 weight% of CaO, 0-25 weight% of SrO, 0-25 weight% of BaO, 0-10 weight% of Na_2O, 0-10 weight% of K_2O, 0.5-10 weight % of Na_2O + K_2O, and 3-40 weight% of CaO + SrO + BaO.;COPYRIGHT KIPO 2011
