A Diopside is known as of excellent thermal properties, but is not high enough to apply to the LED packaging materials. Because the heat is not released out of the LED device, so the chip and PCB (printed circuit board) will be deteriorated. In this study, glass frit of a CaO-MgO-SiO 2 system of stoichiometric diopside composition with the addition of various types and amount of ZnO were fabricated. Effect on the thermal conductivity, density, and shrinkage as a function of various types of ZnO

Effects of ZnO on the density, shrinkage and thermal conductivity were analyzed to investigate the utilizing diopside-based glass-ceramics in LED packaging applications.
