Effect of Hollow Perlite on Dielectric Constant and Hardness of Glass composites |
초록 |
Low dielectric materials are required in the electronic materials such as low temperature co-fired ceramic (LTCC), solar cell and display industry for the dielectric loss, the power consumption and the propagation delay time. The proper hardness is also required for the electric devices for maintaining the inner structure of devices. In our study, the perlite which is used as a filler in the composites has been developed for many applications such as a filter, foundries and insulation for its low density and relatively low prices. Hollow perlite is a spherical shape and the empty inside, so that the shape of perlite is able to contribute to the dielectric constant and hardness of the porous solid. We investigated the porous solid of composite composed of hollow perlite and the B2O3-ZnO-P2O5 glass system which is used in electronic devices. We examined the dielectric property of the composites included the perlite as a filler and B2O3-ZnO-P2O5 glass frits with different mixing ratios and fired at 600oC for 30min. The dielectric constant was measured using an LCR meter (E4980A, Agilent, USA) and the hardness was determined by a Vickers Hardness Tester (HM-101, Mitutoya, Japan). The hollow perlite maintains its spherical shape in the composite and influences the dielectric property and hardness. The purpose of our study is to understand the change of dielectric constant and hardness by the different contains of hollow perlite in the porous solid. |
