GLASS-CERAMIC COMPOSITIONS FOR LTCC USING ALUMINIUM PPHOSPATE BASED CERAMIC FILLERS
The present invention relates to a glass-ceramic composition for LTCC, wherein the glass-ceramic composition is produced by mixing a ceramic filler including aluminum phosphate with low alkali glass powder such as pyrex waste glass or the like at a particular componential ratio. More specifically, provided is a glass-ceramic composition including a ceramic filler having a glass frit produced by finely pulverizing pyrex waste glass to have a particle size range of 1 to 5 μm and 10 wt% of aluminum phosphate. The glass-ceramic composition according to the present invention may be simultaneously calcined with a silver (Ag) electrode at a low temperature of 850 to 925°C, has a low dielectric constant, and minimizes electric loss, so as to be applied to an LTCC substrate, a ceramic heater, and a resonator such as a high efficiency filter and a chip inductor. Moreover, according to the present invention, low alkali waste glass such as pyrex is used as a starting material, so environmentally-friendly properties are ensured, and costs taken to produce glass powder are greatly decreased to reduce process costs.
