Low-temperature sintering of -spodumene ceramics with low coefficient of thermal expansion (CTE) was attained using Li2O-GeO2 sintering additive. Single-phase -spodumene ceramics could be synthesized by heat treatment at 1000 degrees C using highly pure and fine amorphous silica, -alumina, and lithium carbonate powders mixture via the solid-state reaction route. The mixture was calcined at 950 degrees C, finely pulverized, compacted, and finally sintered with or without the sintering additive at 800 degrees C-1400 degrees C for 2h. The relative density reached 98% for the sample sintered with 3mass% Li2O-GeO2 additive at 1000 degrees C. Its Young's modulus was 167GPa and flexural strength was 115MPa. Its CTE (from R.T. to 800 degrees C) was 0.7x10(-6)K(-1) and dielectric constant was 6.8 with loss tangent of 0.9% at 5MHz. These properties were excellent or comparative compared with those previously reported for the samples sintered at around 1300 degrees C-1400 degrees C via melt-quenching routes. As a result, -spodumene ceramics with single phase and sufficient properties were obtained at about 300 degrees C lower sintering temperature by adding Li2O-GeO2 sintering additive via the conventional solid-state reaction route. These results suggest that -spodumene ceramics sintered with Li2O-GeO2 sintering additive has a potential use as LTCC for multichip modules.
