摘 要：<正>To improve the reflectance of white dielectrics,titania has been used commercially as a filler in a glass matrix despite its high dielectric constant.However,calcite has some advantages over titania as a filler,such as its low dielectric constant and the low price of the raw material.We fabricated composites with titania and calcite as the filler in a B2O3-ZnO-BaO-P2O5 （BZBP） glass matrix and investigated their dielectric constants and reflectances with an LCR meter and UV-visible spectrometer,respectively.The reflectance of the composites containing calcite and titania as a filler in the BZBP glass was approximately 80%.However,the dielectric constant varied significantly with the filler （titania:10.82±0.45,calcite:3.75±0.06）.From our results, we conclude that it is possible to develop a profitable and highly efficient white dielectric using calcite as a filler for plasma display panels.
